skip over code

[proctk]

The below code sets the size the image should be displayed. The problem is sometimes the value $row['image_name'] could be blank. when its blank i get this error message

 

Warning: getimagesize() [function.getimagesize]: Read error! in /mnt/w0400/d11/s01/b02a5c57/www/familyclick.ca/photos/photos.php on line 114

 

thats because $row['image_name'] is blank.

 

any ideas how to over come this the below is not working

 

if(!$row['image_name'] = ""){
  	$image = "../user_images/".$row['image_name'];
	$tempimg = getImageSize($image);
	$size = $tempimg[3];
	$size = explode("\"",$size);
	$width = $size[1];
	$height = $size[3];

	$newwidth=100;
	$newheight=($height/$width)*100;
  }
  
  if($row['image_name'] = ""){
  	
	$newwidth=100;
	$newheight=90;
  }

if(!$row['image_name'] = ""){

 

should be

 

if(!$row['image_name'] == ""){ ... both places

 

= is the assignment operator

== is the equality operator - http://ca.php.net/manual/en/language.operators.comparison.php

Yep, look out for using '='...you need '==' when using in if statements.

 

You can also try...

 

<?php

if(trim($row['image_name']) != ''){

   $image = "../user_images/".$row['image_name'];
   $tempimg = getImageSize($image);	
   $size = $tempimg[3];
   $size = explode("\"",$size);
   $width = $size[1];
   $height = $size[3];

   $newwidth=100;
   $newheight=($height/$width)*100;
  }

?>
