Hello,

I would like to conditionally insert an image into Page.ss based on the value of $URLSegment and the presence of the image file:

First problem:
I am trying to generate the HTML to display the image and I have inserted the following code into Page.ss.

<img class="center" src="assets/images/$URLSegment.jpg" alt="$Title" width="520" />

However, $URLSegment and .jpg is replaced with blank, ie. src=""assets/images/"

Second problem:
How do I detect the existence of this file in Page.ss so as to only insert the relevant HTML if the file exists?

Cheers,

Gary

Hello,

To resolve this issue I inserted $URLSegment inside curly brackets ('{$URLSegment}').

I hope this helps.

Cheers,

Gary

Optionally, you could make a new function called ImagePath() on your class and use $ImagePath in the template, instead. This would automatically find the relative path, like assets/images/$URLSegment, so you just need to insert <img src="$ImagePath" alt="My image" /> - this avoids the problem of having curly braces in your nice templates. :-)

function ImagePath() {
return 'assets/images/' . $this->URLSegment . '.jpg';
}

<% if ImagePath %>
<img src="$ImagePath" alt="My image" />
<% end_if %>

Thanks Sean - I might just try that.

Initially, I wasn't sure if I could pass a variable back from a function. I have been plugging away at the templating engine at the weekend and have made some breakthroughs - thanks to your support!

Many thanks,

Gary
