looks like it will. &nbsp;I'll try it then let u know!
</div>

<div>
for some reason this code is not working - I have an alert 1st thing in the javascript and it does not appear. &nbsp;What am I doing wrong? 

<pre><code class="code-1 nolinks" id="code-8168271">&lt;?php
&lt;img src='Images/search_button_16.png' alt='View' title='View' id='$tmp' onmouseover='show($a, $tmp1, $tmp2, $tmp3, $tmp4)' onmouseout='hide($a);'&gt;&quot;;
?&gt;
</code></pre>
</div>

<div>
The syntax you posted is not correct, if you enclose the img tag within php tags, you need to use &quot;echo&quot; or something like that to output the HTML tag. Furthermore, variables do not get expanded when written within single quotes, so without checking the above code, this is what needs to be done to make your code snippet working: 
 
&nbsp;
<pre><code class="code-1 nolinks" id="code-8168273">&lt;?php
echo '&lt;img src=&quot;Images/search_button_16.png&quot; alt=&quot;View&quot; title=&quot;View&quot; id=&quot;' . $tmp . '&quot; onmouseover=&quot;show(' . $a . ', ' . $tmp1 . ', ' . $tmp2 . ', ' . $tmp3 . ', ' . $tmp4 . ')&quot; onmouseout=&quot;hide(' . $a . ');&quot;&gt;';
?&gt;
</code></pre>
</div>

Sorry - just learning. 
This works now but there must be something wrong with this function because the alert here is correct, but I put an alert onload in the bbDetails.php and it never gets there. 
bbDetails was working when passing with code attached in first post, so I don't believe it's there. 
Also, I moved the alert to below the .src statement and it never got there, so I'm sure it's in that statement. 
Thanks - you've got me this far - I appreciate it. 

<pre><code class="code-10 nolinks" id="code-8168322">function show(temp, v1, v2, v3, v4)

{
alert(v1+&quot;,&quot;+v2+&quot;,&quot;+v3+&quot;,&quot;+v4);
 document.getElementById(&quot;content&quot;+temp).src = &quot;bbDetails.php?tmp1=&quot;+v1+&quot;&amp;tmp2=&quot;+v2+&quot;&amp;tmp3=&quot;+v3+&quot;&amp;tmp4=&quot;+v4;

 document.getElementById(&quot;tempIn&quot;+temp).style.display=&quot;inline-block&quot;;

}

then bbDetails.phpb (no response on mouseover):
&lt;?php


$tmp1 = &quot;&quot;;

$tmp2 = &quot;&quot;;

$tmp3 = &quot;&quot;;

$tmp4 = &quot;&quot;;

if (isset($_GET[&quot;tmp1&quot;])) {

 $tmp1 = $_GET['tmp1'];

}

if (isset($_GET[&quot;tmp2&quot;])) {

 $tmp2 = $_GET['tmp2'];

}

if (isset($_GET[&quot;tmp3&quot;])) {

 $tmp3 = $_GET['tmp3'];

}

if (isset($_GET[&quot;tmp4&quot;])) {

 $tmp4 = $_GET['tmp4'];

}

echo &quot;tmp1= $tmp1 : tmp2=$tmp2&lt;BR&gt;&quot;;

?&gt;
</code></pre>
</div>

<div>
I think it's the spaces in the v fields.

Thanks for the quick response and great help!

This code takes a huge amount of time to load the thousands of records it might load. 
I've been told to make it call a blank.html so that it does not load all the code in the iframe on load. 
i.e. &nbsp;substitute details.php with a blank.html and then somehow on mouseover, do the actual load to details.php so that basically no load time is sucked up by details.php. 

<pre><code class="code-10 nolinks" id="code-8168252">function show(temp)

{

 document.getElementById(temp).style.display=&quot;inline-block&quot;;

}

function hide(temp) 

{

 document.getElementById(temp).style.display=&quot;none&quot;;

}

&lt;div class='divclass'&gt;&lt;b&gt; 
&lt;img src=&quot;Images/button&quot; id='test' onmouseover=&quot;show('divname');&quot; onmouseout=&quot;hide('divname');&quot;&gt;

&lt;/td&gt;&lt;td&gt;

 &lt;div id=&quot;display&quot; style=&quot;border:0;display:none;position:absolute;&quot;&gt;

 &lt;iframe src=&quot;details.php?tmp1=xxx&amp;tmp2=yyy&amp;tmp3=aaa&amp;tmp4=bbb&quot;&gt;&lt;/iframe&gt;

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
