I am trying to get the $_POST data from some inputs fields, but the thing is I am getting the number of fields from my database:
$query2 = $DB->prepare("SELECT * FROM params WHERE modulid = $parameterid");
$query2->execute();
<td>Parameter unit:</td>
<?php while (($row2 = $query2->fetch()) != false)
{
$unit = $row2->name;
?><td><input type="text" name="<?php echo $row2->id; ?>" value="<?php echo $unit; ?>" class="textbox"></td><?php
}
?>
What is the code to get post data from all of them so I can update the database if the user wants to type new data in the input?
You can get all values submitted by a form by iterating through the following global variable:
$_POST
By using a foreach loop, you can then check which values were filled and generate an UPDATE SQL statement with them.
Example to get all non-empty values:
$changed = array();
foreach($_POST as $key => $value) {
if(!empty($value)) {
$changed[$key] = $value;
}
}
Then create the query using the $changed array.
Why don't you do something like that
$temp=$row2->id;
mysql_query("insert into params (modulid) values ('$temp')");

I am using David Carr's pagination class successfully for a whole-table call (i.e. where I'm calling all the rows in the table without filtering). After including my config and the class, I accomplish it this way:
$pages = new Paginator('3','p');
$stmt = $dbh->query('SELECT count(id) FROM sermons');
$row = $stmt->fetch(PDO::FETCH_NUM);
$total = $row[0];
//pass number of records to
$pages->set_total($total);
$results = $dbh->query('SELECT * FROM sermons ORDER BY date_preached DESC '.$pages->get_limit()); ?>
<div class="paging"><p><?php echo $total; ?> sermons found</p> <?php echo $pages->page_links();?></div>
<?php
foreach($results as $row)
Etc.
That works great, but now I'm trying to implement it for the result of user filtering via forms, and because I can't use an unnamed placeholder in the query, I'm trying to do it with a prepare (which I'm guessing is more secure anyway):
$pages = new Paginator('2','p');
$series = isset($_POST['series']) ? $_POST['series'] : false;
try {
$stmt = $dbh->prepare("SELECT count(id) FROM sermons WHERE series = ?");
$stmt->execute(array($series));
$row = $stmt->fetch(PDO::FETCH_NUM);
$total = $row[0];
//pass number of records to
$pages->set_total($total);
$results = $dbh->prepare("SELECT * FROM sermons WHERE series = ? ".$pages->get_limit());
$results->bindParam(1, $series, PDO::PARAM_STR);
$results->execute(array($series));
// the call
echo $total; ?> sermons found</p> <?php echo $pages->page_links();
When I first get to the results page from the form, it looks like everything is working properly. The call correctly identifies the number of sermons found for the search result, and displays the first two (or however many I set in the $pages statement). But when I click to another page result, no sermons display, the count is gone, and my !isset(found_rows) echo returns a zero as well.
I was originally thinking the issue was that at first I was trying to do this without binding. That is questionable, since without the pagination I can display the page without binding. In any case, I've been trying that with both bindValue and bindParam, but with no luck.
Am I mishandling something in the prepare statement? Or what?
Note: I have the results page displaying fine without the pagination with this:
$series = isset($_POST['series']) ? $_POST['series'] : false;
try {
$results = $dbh->prepare("SELECT * FROM sermons WHERE series = ?");
$results->execute(array($series));
// Etc.
I want to show the result of this SQL query execution in a view:
$results = Yii::$app->getDb()->createCommand('SELECT * FROM colors')->queryAll();
$people = print_r($results);
<?= $people ?>
But it always shows: 1
The results should be a table with 3 columns and 10 rows. So I don't know why it shows 1. I tried with different tables but always shows the same.
depend of your need you
QueryALL return All rows of the query result.
Each array element is an array representing a row of data
so you could simple iterate over you $result
foreach($result as $key => $row){
echo $row['column1'] . '<br />' ;
echo $row['column2'] . '<br />' ;
....
}
otherwise you can use the queru for build a sqlDataProvider and the manage the models show with widget (eg: gridView)
wrong usage of print_r. see this link. did you mean:
$people = print_r($results, true);
or just use var_dump to avoid confusion.
$results already contains your rows.
This way you'll see this array $results.
$results = Yii::$app->getDb()->createCommand('SELECT * FROM colors')->queryAll();
echo "<pre>";
print_r($results);
exit;
Hi Im trying to insert data into a database using an insert statement. So basically, the user inputs data into a form and then once the submit button is clicked its meant to get the property_id of the table Property.
My code is this:
<?php
$id = intval($_GET['id']);
$query = mysql_query('SELECT * FROM review WHERE property_id="'.$id.'"');
if(isset($_POST['submit']))
{
$review = mysqli_real_escape_string($mysqli, $_POST['review']);
if(mysqli_query($mysqli, "INSERT INTO review(review) VALUES ('$review')"))
{
?>
<script>alert('Successfully Updated ');</script>
<?php
}
else
{
?>
<script>alert('Error...');</script>
<?php
}
}
?>
At the top of the page is my other code which is as followed:
<?php
include_once '../db/dbconnect.php';
$id = intval($_GET['id']);
$sql = 'SELECT* FROM property WHERE property_id="'.$id.'"';
$result = mysqli_query($mysqli, $sql);
$row=mysqli_fetch_array($result);
?>
The code above basically displays all the data for that individual property. Any help would be great.
There are several errors in your code:
$id = intval($_GET['id']);
$query = mysql_query('SELECT * FROM review WHERE property_id="'.$id.'"');
The mysql_* functions are deprecated in PHP 5, and totally removed in PHP 7. Don't use them!
Moreover, it's not possible to use mysql_* and mysqli_* functions together.
Yet another error: you are executing a SELECT query, but you never fetch the results!
Note: you don't need to concatenate $id. It makes the code harder to read with plenty of useless single and double quotes, and increases the likeliness of a typo. Just enclose the variables in a double-quoted string.
You are casting $id to an int value. If the field property_id is an integer, there is no need to put single quotes around $id in the query.
Updated snippet:
$id = intval($_GET['id']);
$query = mysqli_query($mysqli, "SELECT * FROM review WHERE property_id=$id") or die(mysqli_error($mysqli));
while($r = $query->fetch_assoc()) {
// do something here with the current record $r
}
Your code:
if(mysqli_query($mysqli, "INSERT INTO review(review) VALUES ('$review')"))
[...]
<script>alert('Error...');</script>
When developing, you should display (or write to a log file) the MySQL error message from each failing query. It will make debugging much easier:
<script>alert('Error: <?= mysqli_error($mysqli) ?>');</script>
Im using a plugin for CakePHP to make the calls to obtain certain orders. I can call all orders with certain fields, but I was wondering how would I have to make the call to get the orders with a certain name or order_number? Here is the source for the call to Shopify. Its already authenticated and everything:
public function call($method, $path, $params=array())
{
if (!$this->isAuthorized())
return;
$password = $this->is_private_app ? $this->secret : md5($this->secret.$this->ShopifyAuth->token);
$baseurl = "https://{$this->api_key}:$password#{$this->ShopifyAuth->shop_domain}/";
$url = $baseurl.ltrim($path, '/');
$query = in_array($method, array('GET','DELETE')) ? $params : array();
$payload = in_array($method, array('POST','PUT')) ? stripslashes(json_encode($params)) : array();
$request_headers = in_array($method, array('POST','PUT')) ? array("Content-Type: application/json; charset=utf-8", 'Expect:') : array();
$request_headers[] = 'X-Shopify-Access-Token: ' . $this->ShopifyAuth->token;
list($response_body, $response_headers) = $this->Curl->HttpRequest($method, $url, $query, $payload, $request_headers);
$this->last_response_headers = $response_headers;
$response = json_decode($response_body, true);
if (isset($response['errors']) or ($this->last_response_headers['http_status_code'] >= 400))
throw new ShopifyApiException($method, $path, $params, $this->last_response_headers, $response);
return (is_array($response) and (count($response) > 0)) ? array_shift($response) : $response;
}
private function shopApiCallLimitParam($index)
{
if ($this->last_response_headers == null)
{
return 0;
}
$params = explode('/', $this->last_response_headers['http_x_shopify_shop_api_call_limit']);
return (int) $params[$index];
}
...and the code that makes the GET call:
// I only want the id and title of the collections
$fields = "fields=name,id,status,financial_status,fulfillment_status,billing_address,customer";
// get list of collections
$custom_collections = $this->ShopifyAPI->call('GET', "/admin/orders.json", $fields);
$this->set('collections', $custom_collections);
I think I'm missing the place where I can put the conditions for the call to get certain orders. I've already read the API documentation but can't seem to get the answer.
I've tried putting the ?name=%231001 on the url after .json to try and get the order #1001, but it brings back a empty array.
Then I tried ?order_number=1001 but it brings me every order with as well 1001 D: This is really confusing, Could anyone help me?
Thanks in advance.
Well I found out that you can actually get the order using the name or order_number. Its another property that is not listed on the documentation for some reason. But in the URL, if your using another language, all you have to add in the GET is admin/order.json?name=%2310001&status=any this is to get the order 10001 so just add the order_number after the %23. I saw this on a forum in Shopify university, I was just implementing this wrong on my code. If your using the CakePhp shopify plugin like me all I did was add on the $field the ?name=%23". number ."&status=any";
Ill leave the code here:
$this->layout = 'main';
$order_number = "18253";
$fields = "name=%23". $order_number ."&status=any";
$order = $this->ShopifyAPI->call('GET', "/admin/orders.json", $fields);
if (!empty($order)) {
$this->set('order', $order);
} else {
$this->Session->setFlash('<button type="button" class="close" data-dismiss="alert" aria-label="Close"><span aria-hidden="true">×</span></button> No existe el numero de orden ingresado.','default',array('class' => 'alert alert-danger alert-dismissible', 'type' => 'alert'));
}
Hope this helps someone :P
Below is my code:
<?php
$url = $_GET['url'];
$wordlist = array("Www.", "Http://", "Http://www.");
foreach ($wordlist as &$word) {
$word = '/\b' . preg_quote($word, '/') . '\b/';
}
$url = preg_replace($wordlist, '', $url);
?>
<?php
$oDB = new PDO('mysql:dbname=mcnsaoia_onsafe;host=localhost;charset=utf8', 'mcnsaoia_xx', 'PASSWORD');
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside AND godkendt=ja");
$hStmt->execute(array('hjemmside' => $url));
if( $row = $hStmt->fetch() ){
echo "EXIST";
}else{
echo "NOT EXIST";
}
?>
My problem is that it says NOT EXIST, because I know that there is a row which should be found with the following query:
SELECT * FROM users WHERE hjemmside = :hjemmside AND godkendt=ja
So why does it say not exist? I have absolutely no idea :(
Instead of
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside
AND godkendt=ja");
try
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside
AND godkendt='ja'");
The left is most likely a column and the right side is a string? I don't speak your language, but this is the first thing coming to my mind.
You should surround with quotes your not integer variable in your query
AND godkendt='ja'
Or maybe let pdo deal with it
$hStmt=$oDB->prepare("SELECT * FROM users WHERE hjemmside = :hjemmside AND godkendt = :ja");
$hStmt->execute(array(':hjemmside' => $url, ':ja' => 'ja'));
//^ i added : for placeholder here, you missed it
I would also rather check if rows are returned
if($hStmt->$eowVount() > 0){
$row = $hStmt->fetch()
echo "EXIST";
}else{
echo "NOT EXIST";
}
