How can I check in theme's .tpl file with "If" operator is there enabled module(s) in a certain hook?
{if !empty($hook_name)}
{$hook_name}
{/if}
I do not still find any reason to do this checking. But anyway, there is a solution.
Surround your code in template by:
{if $some_modules_enabled}
...
{/if}
And put the below code in a controller, ex: FrontController.php
$id_hook = Hook::get($name_of_the_hook);
$some_modules_enabled = false;
foreach ( Hook::getModulesFromHook($id_hook) as $row ) {
if ( Module::isEnabled( $row['name'] ) ) {
$some_modules_enabled = true;
break;
}
}
$this->context->smarty->assign('some_modules_enabled', $some_modules_enabled);

Following the answer on this post I was using #:<div class="col-md-6">
Problems
The Formatting gets all messed up:
The intellicode gets all messed up (I only deleted the paragraph on the second #:)
Also, my if (i == (Model.CellsNotStarted.Count - 1) && i % 2 != 0) won't work when using the #:; it will always go on the else. If I don't use the #: markup, and if I, for instance put all my html in a if/else instead of only the <div> tag it will work with no problems.
My question is:
Is the #: markup viable? If so, what am I doing wrong. If not what is the alternative (that does not imply putting my entire code in an if/else)
PS: I know I should not post images of code, but I wanted to show the format and syntax errors.
There are neater ways to manage conditions within your Razor code. It's difficult to provide a full example because you don't provide the full code, but you can do this, for example:
<div class="col-md-#(i+1 == Model.CellsNotStarted.Count && i % 2 ! = 0 ? "12" : "6")">
Whenever you are tempted to use a remainder operator (%) in Razor, you should also consider whether a GroupBy would be better. It most often is, as I was shown in this question: Building tables with WebMatrix
You can try to use js to set html.Here is a demo:
<div id="myDiv"></div>
<script>
$(function () {
var html = "";
if ("#(Model.CellsNotStarted != null)"=="True")
{
for (var i = 0; i <#Model.CellsNotStarted.Count; i++)
{
if (i == (#Model.CellsNotStarted.Count - 1) && i % 2 != 0)
{
html += '<div class="col-md-12">';
}
else
{
html += '<div class="col-md-6">';
}
html += i+'</div>';
}
}
$("#myDiv").html(html);
})
</script>
result:
Currently the wishlist module in my Prestashop store only displays the product image and title. There are two wishlist views, the customer account view and the shared link view. I would like to display the price in both of these views. I've tried adding
$price = Product::getPriceStatic($productid);
to different parts of managewishlist.php and adding
<span id="our_price_display">{convertPrice price=$productPrice}</span>
to the managewishlist tpl file but nothing shows up. I'm running version 1.5.6.2.
EDIT: I also tried adding
{if !$priceDisplay || $priceDisplay == 2}
{assign var='productPrice' value=$product->getPrice(true, $smarty.const.NULL, $priceDisplayPrecision)}
{assign var='productPriceWithoutReduction' value=$product->getPriceWithoutReduct(false, $smarty.const.NULL)}
{elseif $priceDisplay == 1}
{assign var='productPrice' value=$product->getPrice(false, $smarty.const.NULL, $priceDisplayPrecision)}
{assign var='productPriceWithoutReduction' value=$product->getPriceWithoutReduct(true, $smarty.const.NULL)}
{/if}
to managewishlist.tpl but it made the wishlist disappear
Not sure about the actual files you need to edit but this should be right for PS 1.5.x
in blockwishlist/view.php add the commented line:
for ($i = 0; $i < sizeof($products); ++$i)
{
$obj = new Product($products[$i]['id_product'], false, $context->language->id);
if (!Validate::isLoadedObject($obj))
continue;
else
{
if ($products[$i]['id_product_attribute'] != 0 && isset($combination_imgs[$products[$i]['id_product_attribute']][0]))
{
$combination_imgs = $obj->getCombinationImages($context->language->id);
$products[$i]['cover'] = $obj->id.'-'.$combination_imgs[$products[$i]['id_product_attribute']][0]['id_image'];
}
else
{
$images = $obj->getImages($context->language->id);
foreach ($images AS $k => $image)
{
if ($image['cover'])
{
$products[$i]['cover'] = $obj->id.'-'.$image['id_image'];
break;
}
}
if (!isset($products[$i]['cover']))
$products[$i]['cover'] = $context->language->iso_code.'-default';
}
// ADD THIS LINE!
$products[$i]['price'] = Product::getPriceStatic($obj->id);
}
}
then in view.tpl (not sure if PS 1.5.x uses the /templates/view/ dir or not try both) you can just use {convertPrice price=$product.price} wherever you need.
Haven't actually tested this but it should give you a good starting point at least.
EDIT Also please be aware that that editing module files directly is not recommended. However, since there is no option to override modules in PS 1.5.x your only options are:
a) editing module directly - meaning it will break if / when you update said module
b) copying the module and renaming it - which is messy but imho preferable to the downside of a)
I'm working with WHMCS and I notice that list views are not working well.
That's because in the clientarea's list views I have tousans thousands of records to display and the DataTables is crashing.
Is there a way to paginate from the server-side? I will appreciate any idea.
Here is an idea: let' say you are viewing the Domains list page, you can use ClientAreaPage hook to create a variable to load a "paged" copy of domains:
add_hook( 'ClientAreaPage', 1, function( $vars )
{
$myVars = array();
if (App::getCurrentFilename() == 'clientarea' && isset($_GET['action']) && $_GET['action'] == 'domains') {
$domains2 = array();
foreach($vars['domains'] as $k => $domain) {
if ($k < 3) {//your code to handle pagination
$domains2[] = $domain;
}
}
$myVars['domains2'] = $domains2;
$myVars['currentpage'] = 1;
}
return $myVars;
});
In clientareadomains.tpl (template file), you need to change $domains to $domains2:
{foreach key=num item=domain from=$domains2}
Of course, it is not simple task, you need to handle pagination in the hook and the tpl files.
Hope it helps.
I have an issue with my php photo upload script. When I upload a file that exceeds 2mb, it won't show that error when I click upload..yet it's there in my script..any idea why this is? For ex. I uploaded a .wma file and It was 2.38MB..that exceeds the limit..but yet it just says "file type not allowed" why didn't it show the exceeds 2mb error as well?
Here is my script:
<?php
include 'init.php';
if(!logged_in()){
header('Location: index.php');
exit();
}
include 'template/header.php';
?>
<h3>Upload Image</h3>
<?php
if(isset($_FILES['image'], $_POST['album_id'])){
$image_name = $_FILES['image']['name'];
$image_size = $_FILES['image']['size'];
$image_temp = $_FILES['image']['tmp_name'];
$allowed_ext = array('jpg', 'jpeg', 'png', 'gif');
$image_ext = strtolower(end(explode('.', $image_name)));
$album_id = $_POST['album_id'];
$errors = array();
if (empty($image_name) || empty($album_id)){
$errors[] = 'Something is missing';
} else {
if(in_array($image_ext, $allowed_ext) === false){
$errors[] = 'File type not allowed';
}
if($image_size > 2097152){
$errors[] = 'Maximum file size is 2MB';
}
if(album_check($album_id) === false){
$errors[] = 'Couldn\'t upload to that album';
}
}
if(!empty($errors)){
foreach ($errors as $error){
echo $error, '<br />';
}
} else {
// upload image
}
}
$albums = get_albums();
if(empty($albums)){
echo '<p>You don\'t have any albums. Create an album</p>';
} else {
?>
<form action="" method="post" enctype="multipart/form-data">
<p>Choose a file:<br /><input type="file" name="image" /></p>
<p>
Choose an album:<br />
<select name="album_id">
<?php
foreach ($albums as $album){
echo '<option value="', $album['id'], '">', $album['name'], '</option>';
}
?>
</select>
</p>
<p><input type="submit" value="Upload" /></p>
</form>
<?php
}
include 'template/footer.php';
?>
Thanks again for all of the patience with my probably easy posts for a lot of you more experienced programmers out there!

As per code, it should, if uploaded file size is >2mb. However, computers never make mistake but the human and thus debugging is important.
Just replace the code
if($image_size > 2097152){
$errors[] = 'Maximum file size is 2MB';
}
with debug statements
if($image_size > 2097152){
echo "in if, image size=".$image_size;
$errors[] = 'Maximum file size is 2MB';
} else {
echo "in else, image size=".$image_size;
}
This is just a first step of debugging. It may or may not fix the real cause. Let us know the output.
Edit after comment:
Put that code in the starting of the file.
echo "files<pre>";
print_r($_FILES);
echo "</pre>imgsz=".$_FILES['image']['size'];
What is the output. I guess it might include
[error] => 1
If it show error=1, Check http://php.net/manual/en/features.file-upload.errors.php
That mean your upload_max_filesize in php.ini is set to 2MB or less. As soon as person upload file bigger than that, it never reach your code as PHP reject the file by default.
To fix that, open php.ini and increase the limit of upload_max_filesize.
Edit 3 after comment
Change
if($image_size > 2097152){
to
if($_FILES['image']['error']==1){
That will fix the issue.
I am using TCPDF to generate the PDF in one of my projects. I simply create a HTML file and give it to the TCPDF to handle the PDF generation. But now I have some HTML where multiple certificates are added one after the other and I want to have a page break in it. Page Break should be decided by HTML i.e. I want to know if there is any identifier in HTML which TCPDF understands and then accordingly adds a page break into the generated PDF.
How could I do this?
I'm using <br pagebreak="true"/>.
Find method writeHTML and code
if ($dom[$key]['tag'] AND isset($dom[$key]['attribute']['pagebreak'])) {
// check for pagebreak
if (($dom[$key]['attribute']['pagebreak'] == 'true') OR ($dom[$key]['attribute']['pagebreak'] == 'left') OR ($dom[$key]['attribute']['pagebreak'] == 'right')) {
// add a page (or trig AcceptPageBreak() for multicolumn mode)
$this->checkPageBreak($this->PageBreakTrigger + 1);
}
if ((($dom[$key]['attribute']['pagebreak'] == 'left') AND (((!$this->rtl) AND (($this->page % 2) == 0)) OR (($this->rtl) AND (($this->page % 2) != 0))))
OR (($dom[$key]['attribute']['pagebreak'] == 'right') AND (((!$this->rtl) AND (($this->page % 2) != 0)) OR (($this->rtl) AND (($this->page % 2) == 0))))) {
// add a page (or trig AcceptPageBreak() for multicolumn mode)
$this->checkPageBreak($this->PageBreakTrigger + 1);
}
}
You might use TCPDF's AddPage() method in combination with explode() and a suitable delimiter:
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8',
false);
// TCPDF initialization code (...)
$delimiter = '<h1>';
$html = file_get_contents('./test.html');
$chunks = explode($delimiter, $html);
$cnt = count($chunks);
for ($i = 0; $i < $cnt; $i++) {
$pdf->writeHTML($delimiter . $chunks[$i], true, 0, true, 0);
if ($i < $cnt - 1) {
$pdf->AddPage();
}
}
// Reset pointer to the last page
$pdf->lastPage();
// Close and output PDF document
$pdf->Output('test.pdf', 'I');
I tried using
<br pagebreak="true" />
or
<tcpdf method="AddPage" />
each of them resulted not in starting new page at the top of the page but adding the full A4-page empty space in between HTML text. So if text ended in the middle of the page and then page break was inserted, the new text was written from the middle of the next page. Which I didn't want.
What worked was this (found it here TCPDF forcing a new page):
$pdf->writeHTML($content, true, 0, true, 0);
$pdf->AddPage();
$pdf->setPage($pdf->getPage());
This now starts with writing text on top of the page.
TCPDF support the 'pagebreak' attribute for HTML tags and CSS properties 'page-break-before' and 'page-break-after'.
For example you can use <br pagebreak="true" />.
Check the official http://www.tcpdf.org website and forums for further information.
With version 5.9.142 from 2011-12-23 we could use the page-break-before, page-break-inside css properties, like this:
<div style="page-break-inside:avoid;">
some non breakable text
</div>
For someone who still has the same problem with page-break TCPDF library
You can use <div style="page-break-before:always"></div> OR <br pagebreak="true"/>
to break page manually in your HTML content.
Use $tcpdf->AddPage() to break page manually in your code.
When you set SetAutoPageBreak(TRUE, 10); that means: when the height of document reach to (bottom - 10) then move the cursor to new page. So if you want to have more space, just reduce the number into 0. It will draw until the end of the document without any margin from bottom.
Remember that TCPDF only accept the double quote (") for attributes of tags. Don't use single quote (') for your tag.
<div style='page-break-before:always' => WRONG
<div style="page-break-before:always" => RIGHT
It takes 8 hours from me because this issue :(
According to http://www.tcpdf.org/examples/example_049.phps you can use something like this
$html .= '<tcpdf method="AddPage" /><h2>Graphic Functions</h2>';
You need to verify that parameter K_TCPDF_CALLS_IN_HTML in TCPDF configuration file is true.
You can also follow this method to accomplish your needs:
$htmlcontent1="CERTIFICATE NUMBER 1 IMAGE HERE";
// output the HTML content
$pdf->writeHTML($htmlcontent1, true, 0, true, 0);
// reset pointer to the last page
$pdf->lastPage();
// - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
// Print a table
// add a page
$pdf->AddPage();
$htmlcontent1="CERTIFICATE NUMBER 1 IMAGE HERE";
// output the HTML content
$pdf->writeHTML($htmlcontent1, true, 0, true, 0);
// reset pointer to the last page
$pdf->lastPage();
// ---------------------------------------------------------
//Close and output PDF document
$pdf->Output('textcertificate.pdf', 'D');
Hopes it helps someone :)
Thanks
Giving your element the page-break-after, page-break-before or page-break-inside property via CSS will apply the attribute pagebreak or pagebreakafter to the html tag during TCPDF runtime.
// page-break-inside
if (isset($dom[$key]['style']['page-break-inside']) AND ($dom[$key]['style']['page-break-inside'] == 'avoid')) {
$dom[$key]['attribute']['nobr'] = 'true';
}
// page-break-before
if (isset($dom[$key]['style']['page-break-before'])) {
if ($dom[$key]['style']['page-break-before'] == 'always') {
$dom[$key]['attribute']['pagebreak'] = 'true';
} elseif ($dom[$key]['style']['page-break-before'] == 'left') {
$dom[$key]['attribute']['pagebreak'] = 'left';
} elseif ($dom[$key]['style']['page-break-before'] == 'right') {
$dom[$key]['attribute']['pagebreak'] = 'right';
}
}
// page-break-after
if (isset($dom[$key]['style']['page-break-after'])) {
if ($dom[$key]['style']['page-break-after'] == 'always') {
$dom[$key]['attribute']['pagebreakafter'] = 'true';
} elseif ($dom[$key]['style']['page-break-after'] == 'left') {
$dom[$key]['attribute']['pagebreakafter'] = 'left';
} elseif ($dom[$key]['style']['page-break-after'] == 'right') {
$dom[$key]['attribute']['pagebreakafter'] = 'right';
}
}
