Show image if exists

Hi
Im using the new UE + DFP extension for the first time after using ADDT (Interakts) extension for this previously.

Problem is in the old ADDT there was a Show if file exist behaviour but in DFP there is not so any ideas how to make the image show only if it exists otherwise do something else ie show a default image or just simply "no image available"

the code for displaying my image is

<img src="../uploaded_images/thumbs/<?php echo $row_WADAproducts['ProductThumb']; ?>" alt="<?php echo $row_WADAproducts['ProductName']; ?>" width="120" border="1" />

Is there an amendement I can make to do this check?

Thanks

Mike

Right changed the code to this:

<?php
if (file_exists("../uploaded_images/thumbs/" . $row_WADAproducts['ProductThumb'])) {
?>

<img src="../uploaded_images/thumbs/<?php echo $row_WADAproducts['ProductThumb']; ?>" alt="<?php echo $row_WADAproducts['ProductName']; ?>" width="120" border="1" />

<?php
}
?>

It appears to work can anyone see any probs with the coding just in case?

Thanks

That would be the way to accomplish this. If you want to display an alternate image if that one doesn't exist, you would just have to put another image tag in an else statement.

Thanks Jimmy

Hello there! Very helpful!

I was wondering though how to make an html item appear if there is a data to the table and make it disappear if there is not.

For example I am trying to list some company details like so:

Address: <dynamic address>
Telephone: <dynamic telephone>

I want the word "Telephone:" to disappear if the user hasn't filled his telephone.

Any ideas?

Thank you!

there are a few ways you could do this.

i would use a php function called strlen which returns the length of the string.

in a php if statement, use this so that if the length of the sting for the telephone number is > 0 display it, otherwise don't

Hi
Another way is (seems odd at first) if you have the Search for BOSS extension installed you will notice a section in your Add Server Behaviour called Utilities in there there is a "Show Region Utility" you can use that.

you can set it to show a region if a condition is met or not met as the case may be.

Give it a go very useful and easy to use.

There is a free DW extension in DMXzone.com called advanced conditional region which creates "if" clauses automatically. Very easy to use. go?553

Hi
Similar to WA Show Region Utility difference being WA has a dropdown to select the conditions and another box to allow you to compare the first condition too.

ie x = y : x <> y

Very useful and far easier.
