Hi,
Are you trying to use PHP as a client scripting language?
What you are doing cannot be done with plain PHP, you have to invoke
JavaScript or similar to make a HTTP request and then parse it.
Search Google for "AJAX" and you could get it working using that. Prototype
is a easy to use JS library that you can do "AJAX" requests with and then do
what you want with by DOM.

Subject: [PHP] calling a function in the same page
I am trying to call a function from "a href" inside the same page.
this is the code:
echo "<br><br><a href=\"isearch($query)\">More results from Mysite</a>";
// calling the function isearch
function isearch($query)
{$query=urlencode($query);
$request='http://api.search.yahoo.com/WebSearchService/V1/webSearch?appid=Ja
hangir&query=' .urlencode($query). '&output=php&results=100&site=mysite.com;
$response=file_get_contents($request);
if ($response === false) {
die('Request failed');}
$phpobj=unserialize($response);
$count=$phpobj["ResultSet"]["totalResultsReturned"];
if($phpobj["ResultSet"]["totalResultsAvailable"]==0)
{echo "<br>NO RESULTS TO DISPLAY"; }
echo "<tr>"; echo "<h4 style=\"color:#FF0000\" align=\"center\">Results from
Mysite</h4>";
for($i=0;$i<$count;$i++)
{ echo '<pre>';
$no=$i+1;
$url=$phpobj["ResultSet"]["Result"]["$i"]["Url"];
echo "<h3>" ."$no. ". "<a href=\"$url\">" .
$phpobj["ResultSet"]["Result"]["$i"]["Title"] . "</a></h3>"; echo "</tr>";
echo "<tr>"; echo $phpobj["ResultSet"]["Result"]["$i"]["Summary"]; echo
"</tr>";
echo "<br>"; echo "<tr>"; echo "<b>"
.$phpobj["ResultSet"]["Result"]["$i"]["Url"] ."</b>"; echo "</tr>";
echo "<br>"; $link=$phpobj["ResultSet"]["Result"]["$i"]["DisplayUrl"];
echo "<tr>"; echo "<a href=\"$url\">$link</a>"; echo "</tr>";
echo '</pre>'; }}
whenever i try to execute this function i either get an "Object not found
error" or "Access Forbidden error".
Can someone tell me where am i going wrong here??
thanks in advance

Yep, you definitely didn't understand the requirements. Tsk tsk.

Hi,
I have made some script that process the users input, and validates the input
and sends it back. But it doesn't work very
well, in fact it doesn't work at all. I am only able to see and input my name
and such in the html form, but the php part doesn't do it's job.
I have looked over the scripts thousands of times, but couldn't find the
problem, really.
Here is the script plus 2 .inc files;
Hoping for some replies and answers,
Thanks in advance!
PS: if this script is a bit messy to read, I have included them in this mail
seperately.

I cannot get 3rd script. And this one may solve your problem in address form
and info.inc..
<?php
$labels = array( "firstName"=> "First Name:",
"midName"=>"Middle Name:",
"lastName"=>"Last Name:",
"street"=>"Street Address:",
"city"=>"City:",
"state"=>"State:",
"zipcode"=>"Zipcode:");
$strLoop = '';
$intSize = sizeof($labels);
$arrKeys = arrayKeys($labels);
for($l=0;$l<$intSize;$l++)
{
$value = '';
if(isset($_REQUEST[$labels[$arrKeys[$l]]]))
{
$value = $_REQUEST[$labels[$arrKeys[$l]]];
}
$strLoop.=
" <tr>
<td align='right'>
".$labels[$arrKeys[$l]]."<br/>
</td>
<td>
<input type='text'
name='".$arrKeys[$l]."' size='65' maxlength='65'
value='".$value."' />
</td>
</tr>\n";
}
$strPage =
"<html>
<head>
<title>
Customer Address
</title>
</head>
<body>
<p align='center'>
<form action='validateForm.php' method='POST'>
<table width='95%' border='0' cellspacing='0'
cellpadding='2'>
".$strLoop."
<tr>
<td align='center'>
<input type='Submit' name='Submit'
value='Submit Address' />
</td>
</tr>
</table>
</form>
</p>
</body>
</html>\n";
echo $strPage;
?>
validateForm.php
May Look like this
<?php
$intSize = sizeof($_REQUEST);
$arrKeys = array_keys($_REQUEST)
// Or you may use $labels array again
if($intSize > 0)
{
for($r=0;$r<$intSize;$r++)
{
// do some global check for all $_REQUEST elements
// then do some conditional
switch ($_REQUEST[$arrKeys[$r]])
{
case "firstName":
//do Someting
break;
....
}
}
}
?>

Look at the variable names you use for iteration.

The print lines above are supposed to produce a list of links to
files.
In the web display I get duplicate sets of links which seems to mean
that the loops in the function are running twice, and in one instance
three times instead of once.
Look at the variable names you use for iteration.
Thanks, Usually, when a variable name like $i is used and then
reset to 0 in the next loop it does not matter. But I solved the
problem and posted the solution. I also solved the regex
problem. There was an extra \n sneaking into the test pattern
so I could not get a match. I am not sure where the extra \n is
coming from.
It looks like I didn't post the solution after all:
Update:
I solved the double loops problem with this code change:
function display($list, $a, $x)
{
for($i = 0; $i < count($a); $i++)
{$j = $i + 1;
print "<a
href=\"steps.php?list=$list&next=$j&x=$x\">$j</a><br><br>\n";
};
}
and:
if($list || $current)
{
switch($list)
{
case 'in':
display($list, $in, $x);
break;
case 'out':
display($list, $out, $x);
break;
case 'save':
display($list, $save, $x);
break;
case 'req':
display($list, $req, $x);
break;
}
}
Apparently what was happening was that the code running under 5.1.2
was trying to process all the arrays that had values in spite of the
switch
statement in the original display() function. If the was an $in array
the
switch would process that for the $list value being 'in' but since
there
was also a save value, the switch tried to process it also, even though
'save' wasn't the $list value. I found it would do this for all arrays
that
had values. So if three had values the loop selected loop would run
three times.
Could this be a bonafide bug?
