well have them all submit to one page and on that page call functions depending on what was submitted.
eg
<table width="90%" border="1">
<tr>
<td>
<form method="post" action="search.php">Trainer Name:
<input name="TName" type="text" id="TName" maxlength="30">
<input name="button" type="button" value="Search Trainer Names">
</form>
</td>
</tr>
<tr>
<td>
<form method="post" action="search.php">Trainer Area:
<input name="TArea" type="text" id="TArea" maxlength="30">
<input name="button2" type="button" value="Search Trainer Areas">
</form>
</td>
</tr>
<tr>
<td>
<form method="post" action="search.php">Skill Name:
<input name="SName" type="text" id="SName" maxlength="30">
<input name="button3" type="button" value="Search For Skills">
</form>
</td>
</tr>
</table>
// search.php
<?php
if(isSet($_POST['TName'])){
// call corresponding function
}
if(isSet($_POST['TArea'])){
// call corresponding function
}
if(isSet($_POST['SName'])){
// call corresponding function
}
