I have a function that displays the content of a remote folder in a select list. In the folder are images and thumbnail images. I'm trying to figure out how to filter out the thumbnail images because I don't want them appearing in the select list.

My thumbnail filenames all finish like this '_t.jpg', so is there some way I can look for this and then if it's found not display it?

Yup, there are two PHP functions to help you. Also there's more advanced methods using preg match, but these should work just fine.

<ul><li><b>str_replace</b> - wwwphp.net/manual/en/function.str-replace.php</li><li><b>substr_replace</b> - www.php.net/manual/en/function.substr-replace.php</li></ul>

Thanks Chris. I'll have a look at those two functions you mention. After posting I figured out a way of doing it, but your ways might be better. What do you think? This is what I did:

<pre id=code><font face=courier size=2 id=code>$thumbnail = substr($file, -6); //Finds thumbnail suffix and extension
if ($thumbnail != '_t.jpg' and $thumbnail != '_t.gif') {
echo '&lt;option value="',$file,'"'; {
if ($ImageURL == $file) echo ' selected'; echo '&gt;' . $file . '&lt;/option&gt;'; //Lists files and selects one based on database entry
}
}</font id=code></pre id=code>

<BLOCKQUOTE id=quote><font size=1 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote><pre id=code><font face=courier size=2 id=code>$thumbnail = substr($file, -6); //Finds thumbnail suffix and extension
if ($thumbnail != '_t.jpg' and $thumbnail != '_t.gif') {
echo '&lt;option value="',$file,'"'; {
if ($ImageURL == $file) echo ' selected';
echo '&gt;' . $file . '&lt;/option&gt;'; //Lists files and selects one based on database entry
}
}</font id=code></pre id=code><hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

Cool, seems fine. Your <i>if</i> statement uses AND, it could also be OR since it's a .jpg or .gif - but most importantly is <b>are you coding XHMTL</b> or regular HTML? I mention because your <pre id=code><font face=courier size=2 id=code>... echo "selected"...</font id=code></pre id=code>
If XHTML, it should be valid...<pre id=code><font face=courier size=2 id=code>selected="selected"</font id=code></pre id=code>
It's being slightly discussed at:

Also, since you're doing a lot of replace and inserting variables within HTML, you may want to look at PHP's function called <i><b>sprintf</b></i>. I have a free article on it here:

This site is just regular HTML at the mo, but I'm hoping to start creating XHTML sites soon, so thanks for the tip. Once again you've been most helpful. Just printing out your sprintf article now, cheers!
