After trying many things, I found the solution on another forum.
In the menubar.php, this is input:
<p class="sideBarTitle">Forecast Search</p>
<table align="center" cellspacing="0" cellpadding="2" border="0" width="90">
<tr>
<td align="center" colspan="2">Find Your Local NWS Forecast By<br />
</td>
</tr>
<tr align="center" valign="top">
<td class="searchinput">
<form method="post" action="wxsearch.php">
<input type="text" name="where" size="11" value="City, St or Zip" onfocus="this.value='';" />
<input type="submit" name="Go2" value="Go" />
</form>
</td>
</tr>
</table>Then on a page named wxsearch.php:
<iframe src="http://www.srh.noaa.gov/zipcity.php?inputstring=<?php echo $_POST["where"]; ?>"
name="frame1" frameborder="0" width="700" height="1550">
<p>Your browser does not support iframes.</p>
</iframe>This allows visitors to get any NWS forecast with out leaving my site.
