I have a text box as follows:
<input type="text" name="<?php echo $usage;?>">
i want to find out if the user has entered anything into this text box.
i tried $_GET['usage']; but it doesnt work
This seems more like what you might be thinking:
<input type="text" name="usage" value="<?php echo $usage;?>">
View the source after first requesting this form to see what your <input> element looks like. If it shows
<input type="text" name="">then $usage has not yet been populated and actually you should be getting an error, that's if you have error_reporting() [php.net] turned on in your development mode here.
help!

if (isset($_GET)) {
print '<pre>';
print_r($_GET);
print '</pre>';
// or perhaps a foreach loop:
print '<pre>';
foreach ($_GET as $name => $value) {
print "$name: $value\n";
}
print '</pre>';
}
this stuff is inside a while loop : while($row = @mysql_fetch_array($sql))
and just before it $k =0;
and this text box is inside a form with method="get"
<html><head><title>Sample</title></head><body>
<h1>Sample</h1>
<form action="<?php print $_SERVER['PHP_SELF'];?>" method="get">
<fieldset>
<legend>Sample</legend>
<?php
$k =0;
// Don't know what total is, so I set it to 50
$total = 50;
// Just used a for loop for demonstration purposes:
for ($i = 0; $i < 10; $i++) {
$usage = "usage".$k;
$k++;
?>
<input type="text" size="4" name="<?php echo $usage;?>" maxlength="3"
<?php
}
?>
<br /><br />
<input type="submit" name="Submit" value="Submit" />
</fieldset>
</form>
<fieldset>
<legend>Posted Form Values<legend/>
<?php
if (isset($_GET)) {
print '<pre>';
print_r($_GET);
print '</pre>';
// or perhaps a foreach loop:

}
print '</pre>';
}
?>

please ignore the opening closing of tr, td tags cos i have tried to shorten the code for you n there are far too many nested table sin my page (rest assured there is no error in the markup!)
help!
($_GET['usage'])You'd need to check each variable. Using the sample test code above, I changed the foreach to:
foreach ($_GET as $name => $value) {
if (strpos($name,'usage')===FALSE){
print "Not the right variable\n";
} else{
if ($value <> ''){
print "$name: $value\n";
} else {
print "$name: empty\n";
}
}
} baze
