Image Divide by zero error

[LunchBox]

Arrrrrrrrrrgggggggggggghhhhhhhhhhhhh!!!!!

 

I'm now pulling my hair out over this.

 

With my local installation I get no errors at all.

 

Uploaded to my server and when there is no image I'm getting a divide by zero error.

 

I've made a change to resize images.

 

   if ( ($width) && ($height) ) {

    $image_size = @getimagesize($src);

    $ratio = $width / $image_size[0];

    if ($image_size[1]*$ratio > $height) {

      $ratio = $height / $image_size[1];	

      $width = $image_size[0] * $ratio;

    } else {

   $height = $image_size[1] * $ratio;

    }



       $image .= ' width="' . $width . '" height="' . $height . '"';

  }

 

The error is occuring on the third line.

 

Only happens on the web server.

 

Please help.........

What is the result of getimagesize() ?

That is probably your error but the @ stops it from reporting.

Remove the @ and see what it tells you.

I'm quite sure it doesn't return the array with the sizes like expected...

[LunchBox]

Quite right ( as ever :) )

 

It's reporting an error:

 

Warning: getimagesize: Unable to open 'images/Array' for reading. in /home/temptation/www/catalog/includes/functions/html_output.php on line 108

 

Any ideas? Could it be folder permissions?

[mattice]

might be permissions yes... but in this case you have tried to upload an Array as the image path... so in your products table it states 'Array' instead of my_nice_image.jpg...

 

fix that, check the permissions on the folder / images and you should be okay...

*cough* bug on a new product with no image first time through = Array for the image name ...

 

Ian made a nice temp fix for that in the contributions if I am not mistaken.

[LunchBox]

Small problem...

 

It's not happening for a product (although I have found 2 products that do).

 

It's happening between the category title and the product listings...

Look for the Array bit in the categories table.

Nice parachute but I think I'll pass ;)

[LunchBox]

I looked for that too. Nothing there.

 

The image name is AP.C2081.jpg Could that be a problem? The extra Period?

 

Cheers,

[mattice]

Don't think so but you're the one that can check ;)

[LunchBox]

Nope it's not that.

 

What get's drawn there? The category image is being displayed correctly.....

 

I've now got my bum in my hands. Not going to bed until this is fixed. Wife very unhapy.

 

Don't understand why it's working OK on laptop, but not on server.

 

Hmmmmmmmmm.........

 

J.

[mattice]

if so look in the html source on the laptop what is drawing there...

ah... come to think of it:

 

pixel_trans.gif

 

might be it... it used for spacers etc.

[LunchBox]

It appears to be dying in product_listing.php

 

  $list_box_contents = array();

 $list_box_contents[] = array('params' => 'class="productListing-heading"');

 $cur_row = sizeof($list_box_contents) - 1;



 for ($col=0; $col<sizeof($column_list); $col++) {

   switch ($column_list[$col]) {

     case 'PRODUCT_LIST_MODEL':

       $lc_text = TABLE_HEADING_MODEL;

       $lc_align = 'left';

       break;

 

Something to do with this.......???????

 

Help please.

 

J.

[mattice]

don't think so. That code builds the headings but does not call tep_image() which is causing the error... Did you look at the html source on the laptop?

[LunchBox]

Laptop isn't drawing anything.....

 

The server source is....

 

  <tr>

   <td><img src="images/pixel_black.gif" border="0" alt="" width="1" height="1"></td>

 </tr>

 <tr>

   <td>

<br />

<b>Warning</b>:  getimagesize: Unable to open 'images/Array' for reading. in <b>/home/temptation/www/catalog/includes/functions/html_output.php</b> on line <b>108</b><br />

<br />

 

The laptop is...

 

  <tr>

   <td><img src="images/pixel_black.gif" border="0" alt="" width="1" height="1"></td>

 </tr>

 <tr>

   <td>

<table border="0" width="100%" cellspacing="0" cellpadding="2">

 <tr class="productListing-heading">

   <td align="center" class="productListing-heading">  </td>

   <td align="left" class="productListing-heading"> <a href="http://localhost/catalog/default.php?cPath=5_24&page=1&sort=2d" title="Sort products descendingly by Product Name">Product Name+</a> </td>

I'm an idiot. :oops: :stupid:

 

I was expecting the error to occur where the images where missing. But it builds the list first and then displays them.

 

Fixing the Array in the products_images fixed the problem.

 

But why did it not complain on the laptop?

 

A question for another day. I'm going to bed.

 

Thanks for all your help Mattice. I owe you one :)

 

Good Morning.
