ObjectDataSource1.FilterExpression = "userid LIKE '{0}' AND action LIKE '{1}'";
ObjectDataSource1.FilterParameters.Add("userid", ddlUsers.SelectedValue);
ObjectDataSource1.FilterParameters.Add("action", ddlAction.SelectedValue);
I wirte like this code.
when I run it grid view is empty. BUT, when I write and run it works good.
ObjectDataSource1.FilterExpression = "userid LIKE '{0}' AND action LIKE '{Login}'";
ObjectDataSource1.FilterParameters.Add("userid", ddlUsers.SelectedValue);
ObjectDataSource1.FilterParameters.Add("action", ddlAction.SelectedValue);
Without parameters (action)
its shows all login of selected ddlUsers.SelectedValue.
Why does not work like this?
ObjectDataSource1.FilterExpression = "userid LIKE '{0}' AND action LIKE '{1}'";
ObjectDataSource1.FilterParameters.Add("userid", ddlUsers.SelectedValue);
ObjectDataSource1.FilterParameters.Add("action", ddlAction.SelectedValue);
Yes :) I found the problem.
Before this code, I used ObjectDataSource1.FilterParameters.Add("userid", Name); code
so 3 filterParameters.
So this query is empty. Grid View shows empty information.
I remove all parameters and I add just this two parameters and it's ok. It shows very good.

I've searched high and low for an answer on this, but I'm either missing something, or I just can't find anything in this context.
Background - trying to avoid spaghetti frenzy with a little casual project I'm starting; part of this will involve mainly just calls to a mysql database, displaying table content and so on. Simply put, like a CRM I guess.
I may be way off base here, but I want to be able to create my sql calls as functions, which will help if/when I tweak and tune, as well as creating a cleaner code for what I'm looking to do.
So, without further ado, I have this as a demomstration:
echo "<table>";
selectall('actions','content',$mysqli);
echo "</table><br><br>";
What this does is show all rows from my table of 'actions. "content" is just an example field name I'm passing through that I want to display, as it is the main human-relevant field name in that table. I'm also passing $mysqli through here for my function db call.
My function looks like this:
function selectall($s_table,$s_content,$mysqli){
$query = "SELECT * FROM " . $s_table;
$resource = $mysqli->query($query);
if ( !$resource ) throw new Exception($db->error);
while ( $row = $resource->fetch_assoc() ) {
$id = $row['id'];
echo "<tr><td>{$row[$s_content]}</td></tr>";
}
$resource->free();
$mysqli->close();
}
However.... it doesn't work, and it seems to throw a wobbly saying:
Warning: mysqli::query(): Couldn't fetch mysqli
This points to the action within the line $resource = $mysqli->query($query);
I know the function and everything is ok, as if I restate and declare $mysqli within the first line of the function, like so...
$mysqli = new mysqli(username password and so on in here);
... it works spot on.
$mysqli exists and works within the same code that is passing the variable within the function too.
This is early stages, so by shuffling the code around trying to poke the $mysqli pass into life I have perhaps made the code a little messier that intended, so try not to worry too much about that.
Anyone any ideas why it doesn't like this?
D'oh...
I had a
$mysqli->close();
in the lines above. Solved myself.
For reference, this is my function:
function selectall($s_table,$s_field,$mysqli){
if ($mysqli->connect_error) {die('Connect Error (' . $mysqli->connect_errno . ') '. $mysqli->connect_error);}
$s_table = preg_replace('/[^0-9a-zA-Z_]/', '', $s_table); // Cleans up the table name variable
$s_field = preg_replace('/[^0-9a-zA-Z_]/', '', $s_field); // Cleans up the field name variable
$query = "SELECT * FROM " . $s_table; // Adds passed table name to the select all
$resource = $mysqli->query($query);
if ( !$resource ) throw new Exception($db->error);
while ( $row = $resource->fetch_assoc() ) {
echo "<tr><td>{$row[$s_field]}</td></tr>"; // Content for each row of the select all
}
$resource->free();
$mysqli->close();
}
As you can see, I've also tried to protect the variables that enter the function.
This can be called via:
selectall('actions','content',$mysqli);
In this context, I want to view all the entries in the 'actions' table by the field name 'content'. This function, with some code above and below for a table, will create a new row for each entry.
I'll probably evolve a few, already created on that includes a delete button at the end of the line which is 'selectalldel'.
Open to comments on whether this actually is worthwhile, but thought I'd post up my corrected stupidity in case anyone finds this useful.
I am trying to query a database to obtain rows that matches 4 conditions.
The code I'm using is the following:
$result = db_query("SELECT * FROM transportesgeneral WHERE CiudadOrigen LIKE '$origen%' AND DepartamentoOrigen LIKE '$origendep' AND DepartamentoDestino LIKE '$destinodep' AND CiudadDestino LIKE '$destino%'");
But it is not working; Nevertheless, when I try it using only 3 conditions; ie:
$result = db_query("SELECT * FROM transportesgeneral WHERE CiudadOrigen LIKE '$origen%' AND DepartamentoOrigen LIKE '$origendep' AND DepartamentoDestino LIKE '$destinodep'");
It does work. Any idea what I'm doing wrong? Or is it not possible at all?
Thank you so much for your clarification smozgur.
Apparently this was the problem:
I was trying to query the database by using the word that contained a tittle "Petén" so I changed the database info and replaced that word to the same one without the tittle "Peten" and it worked.
Now, im not sure why it does not accept the tittle but that was the problem.
If you have any ideas on how I can use the tittle, I would appreciate that very much.
When a Webhook is triggered, is there a way to get the org_id from which it was fired? (Aside from climbing up the triggered item)
The only solution I found so far is:
PodioItem::get($item_id); to get the space_id
PodioSpace::get($space_id); to get the full
PodioOrganization::get_for_url($attributes = array()); I get the org_id.
See the "Bundling responses using fields parameter" section at the very bottom of https://developers.podio.com/index/api on how you can use the fields query parameter to include more data. There's even an example that goes almost all the way for you (it walks up to the space level, but you can just tack the org onto it):
/item/{item_id}?fields=app.view(full).fields(space.view(full))
For podio-php you can do:
$item = PodioItem::get($item_id, array('fields' => "app.view(full).fields(space.view(full))"));
Use PodioItem::filter instead of PodioItem::get, I'm pretty sure that you'll have the expected results, so try this:
$item = PodioItem::filter($item_id, array('filters' => "app.view(full).fields(space.view(full))"));
Hope it helps!
Using the Andrew Eddie's tutorials here I am working on building some custom code for menus. Here we go:
$query ->select('id, menutype, title')
->from('#__menu_types')
->where('menutype='.$somemenu);
$db->setQuery($query);
I don't know how to load one object value like I used to do it with Joomla 1.5:
$result = $db->loadObject();
$thetitle = $result->title; // I need this value and I always get error "Notice: Trying to get property of non-object" at this line
How can I SUCCESSFULLY get the value of $thetitle please?
That should work. I see no problem with your code.
The error you are getting is consistent with not having found a match in the database.
Since you do not appear to have any error handling it might even be an SQL error.
Try and add this:
if ($error = $db->getErrorMsg()) {
throw new Exception($error);
}
The correct query is
$query ->select('id, menutype, title')
->from('#__menu_types')
->where('menutype='.$db->quote($somemenu));
$db->setQuery($query);
Now I can get the values of the query correctly.
I was wondering how I would go about checking to see if a table contains a value in a certain column.
I need to check if the column 'e-mail' contains an e-mail someone is trying to register with, and if something exists, do nothing, however, if nothing exists, insert the data into the database.
All I need to do is check if the e-mail column contains the value the user is registering with.
I'm using the RedBeanPHP ORM, I can do this without using it but I need to use that for program guidelines.
I've tried finding them but if they don't exist it returns an error within the redbean PHP file. Here's the error:Fatal error: Call to a member function find() on a non-object in /home/aeterna/www/user/rb.php on line 2433
Here's the code that I'm using when trying this:
function searchDatabase($email) {
return R::findOne('users', 'email LIKE "' . $email . '"');
}
My approach on the function would be
function searchDatabase($email) {
$data = array('email' => $email);
$user = R::findOne('users', 'email LIKE :email, $data);
if (!empty($user)) {
// do stuff here
} // end if
} // end function
It's a bit more clean and in your function
Seems like you are not connected to a database.
Have you done R::setup() before R::find()?
RedBeanPHP raises this error if it can't find the R::$redbean instance, the facade static functions just route calls to the $redbean object (to hide all object oriented fuzzyness for people who dont like that sort of thing).
However you need to bootstrap the facade using R::setup(). Normally you can start using RB with just two lines:
require('rb.php'); //cant make this any simpler :(
R::setup(); //this could be done in rb.php but people would not like that ;)
//and then go...
R::find( ... );
I recommend to check whether the $redbean object is available or whether for some reason the code flow has skipped the R::setup() boostrap method.
Edited to account for your updated question:
According to the error message, the error is happening inside the function find() in rb.php on line 2433. I'm guessing that rb.php is the RedBean package.
Make sure you've included rb.php in your script and set up your database, according to the instructions in the RedBean Manual.
As a starting point, look at what it's trying to do on line 2433 in rb.php. It appears to be calling a method on an invalid object. Figure out where that object is being created and why it's invalid. Maybe the find function was supplied with bad parameters.
Feel free to update your question by pasting the entirety of the find() function in rb.php and please indicate which line is 2433. If the function is too lengthy, you can paste it on a site like pastebin.com and link to it from here.
Your error sounds like you haven't done R::setup() yet.
My approach to performing the check you want would be something like this:
$count = count(R::find('users', 'email LIKE :email', array(':email' => $email)));
if($count === 0)
{
$user = R::dispense('users');
$user->name = $name;
$user->email = $email;
$user->dob = $dob;
R::store($user);
}
I don't know if it is this basic or not, but with SQL (using PHP for variables), a query could look like
$lookup = 'customerID';
$result = mysql_fetch_array(mysql_query("SELECT columnName IN tableName WHERE id='".$lookup."' LIMIT 1"));
$exists = is_null($result['columnName'])?false:true;
If you're just trying to find a single value in a database, you should always limit your result to 1, that way, if it is found in the first record, your query will stop.
Hope this helps
