Hi Guys,

I need help I have setup a code recently :

this is the code :
$za['MIN(spec_positionid)']

and it gave me an error saying : Cannot use object of type stdClass as array

but if I change to this :

$za->spec_positionid

it works, but I need to get the MIN value from the database.

can someone please help.

this is very urgent for me.....

I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

Just started.  I am pretty sure composer.json wasn't changed.  journalctl doesn't show anything.  Maybe Doctrine related, however, nothing seems to help.

Any ideas?

Hi everyone,

I have some code which has been successfully zipping up the contents of a folder full of images. However, whilst playing around with some other things on the site, I seem to have broken it! The error message I get is...

Code: [Select]
<b>Warning</b>:  ZipArchive::addFile() [<a href='ziparchive.addfile'>ziparchive.addfile</a>]: Invalid or unitialized Zip object in <b><server path to my file>/gallery/includes/classes/hwGallery.php</b> on line <b>195</b><br />
Could anyone please explain what might be causing this? I'm sure the object is being initialised OK, as it's exactly the same code as previously, which worked in the past, although now even that seems to have broken (i.e. uploading an old version of the code, which used to work, also now fails). Could this be a file permissions error? I'm not entirely sure where PHP would be writing the file (does it even do that, or is it all carried out in memory?). Any pointers or helpers would be gratefully received - Google and the search feature on this site haven't turned up anything so far.

Thanks,
Haydn

Code:
The code to get the zip file is part of the 'hwGallery' class...
Code: [Select]
/*
* Create a ZIP file containing all the images in the gallery
*
*/
public function getZipFile() {

// Partially taken from http://ubuntuforums.org/showthread.php?t=859477

// Zip file header
header("Content-Type: application/zip");
header('Content-Disposition: attachment; filename="gallery.zip"');

// Create actual Zip file
$zipFile = new ZipArchive();
$zipFile->open("download.zip", ZipArchive::OVERWRITE);
foreach ($this->imagePaths as $imageFile) {
if (strpos($imageFile,"index") == false) {
$zipFile->addFile($imageFile);
}
}
$zipFile->close();

// Return the ZIP file, then delete it
echo file_get_contents("download.zip");
unlink("download.zip");

}

which is called in the following manner:

Code: [Select]
$gallery = new hwGallery($id);
$gallery->getZipFile();

I have a registration form on my website and after Registration I want the user to activate first his account. I don't have problem on sending this email to the user. What I want to appear is like this..

GoodDay "username",

Blah Blah!

how can you actually do that? I know that you can do that through session variables but the thing is email's can't accept scripts on sending emails. how can I get the value from a session variable for example and convert it to plain html text so that i can OUTPUT it to the email.. HELP PLEASE!

Hi, I currently have an if, elseif, else program that starts off with

Code: [Select]
if( $v_name == "" || $v_msg == "" )
echo "something"
how do I turn this into a switch?

but the very next elseif I have

Code: [Select]
elseif( strcspn( $_REQUEST['msg'], '0123456789' ) == strlen( $_REQUEST['msg'] ) )
echo "something"

is it possible to turn this into a switch with 2 different strings like that to evaluate?

I made a small script and it says that my database object isn't an object.

I connect to my pdo database via:

<?php

try {
$db = new PDO("mysql:host=localhost;dbname=database", "root", "root"); 
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 
}  
catch(PDOException $e) {  

echo $e->getMessage();
  
}

?>

 

The error I get is

Code: [Select]
Notice: Undefined variable: db in /Users/JPFoster/Sites/jobiji_sandbox/extensions/tasks.php on line 21

Fatal error: Call to a member function query() on a non-object in /Users/JPFoster/Sites/jobiji_sandbox/extensions/tasks.php on line 21


here's where the error is
$grabber = $db->query('SELECT * WHERE user_id =' . $userid);
$grabber->setFetchMode(PDO::FETCH_OBJ);

while ( $row = $grabber->fetch() ){

$display = '<div>Task Name: ' . $row->name .'</div>';
$display .= '<div>Task Details: <p>'. $row->details  .'</p></div>';
//$display .= '<div>'. $this->checkifDone($row->task_status) .'</div>';
$display .= '<div>Task Due: '. $row->task_due . '</div>';
echo $display;
}


could anyone tell me where this issue is originating I followed a fairly simple tutorial that didn't seem to work.


Thanks!

Hi all,

Using a form with check boxes divided into different categories, I collect data selected by the user.

I now want to combine each choice in each category with each choice in the other categories and list the combinations to the user.

If the user chooses one or more options in each category, it is relatively easy to nest foreach loops, since the number of categories will always be the same. For example, if the form contains three categories of options, the code will be:

Code: [Select]
foreach ($form['cat_1'] as $k1 => $val1)
{
foreach ($form['cat_2'] as $k2 => $val2)
{
foreach ($form['cat_3'] as $k3 => $val3)
{
echo  $val1.' _ '.$val2.' _ '.$val3.'<br/>';
}
}
}

Things get complicated if the user does not select options within a given category. More generally, I want to be able to generate the list regardless of the number of categories in which the user selects options.

Thank you in advance for your advice.

Hey guys!
I have the following doubt:

I have a php file that does the following alongside with other code not displayed he

$fp = fopen("emails.txt", "w");

It opens a txt file called emails.txt that is in the same folder where the php is saved but how do I tell $fp = fopen("/folderbefore/emails.txt", "w"); ??

In other words, how do I write the path on the script that the emails.txt is located in a previous folder where the php file is located??

Thanks in advance for your help
Cheers!

hello,

I was wondering what is the point of writing

for a dropdown: <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?>

or for a checkbox/ radio button: <?php if ($_POST['cb/radioID'] == "value") { echo "checked"; } ?>

I guess it's for after submit, if there is any error, the values filled will still be echoed in the inputfield, or am i wrong?

But then if that is true, i have a php search box where i use AJAX object to to send all the input they filled in after submit. But after pushing submit the inputted values remain.

I guess when using AJAX to send the information i don't need  <?php if ($_POST[inputfieldID] == "value") { echo "selected"; } ?> in my html forms?


Little confused Can maybe somebody bring clearness

I'm a very new PHP user (as in, I just started today) and need to make a set of navigation buttons which will take the user to "next" or "previous" pages. I assume that the $_GET function is involved, but I don't know how to do it.

It needs to work like this:

If the URL looks like "http://website.com/page1.php"

I need the "next" button (a href image) to change it to "/page2.php", and while on page 2, for the "previous" button to take the user to "/page1.php" and so forth. How can I cause the page number to increment or decrease respective to the href image being clicked?
