determine number of entries Options (2)

31/01/2008, 13h20

This is a followup to a previous question.

I have a form with a series of sequentially named input controls

<input type='text' name='IngQty1'
onChange='javascript:saveValue(1,this.value)'>
<input type='text' name='IngQty2'
onChange='javascript:saveValue(2,this.value)'>
<input type='text' name='IngQty3'
onChange='javascript:saveValue(3,this.value)'>
....

I am trying to count the number of instances of inputs IngQty# and
also loop through the values.

In a response (see http://groups.google.com/group/php.g...0f072bf291bda4)
I got previously I was given the following

foreach($_SERVER['POST']['foo'] as $key => $value) {
//do something with each one

}

count($_SERVER['POST']['IngQty'])

but it doesn't work (I should rephrase that and say I can't get it to
work).

The for each generates a "Warning: Invalid argument supplied for
foreach()" and the count always returns a value of 0.

Could someone me get these functional.

Thank you for the !

If what you've got above is what you're using I wouldn't expect it to
work. You still have your form elements named IngQty1, IngQty2, etc.
You need to use IngQty[1], IngQty[2], etc. Then, your foreach should
look something like this:

foreach($_SERVER['POST']['IngQty'] as $key => $value)

Of course, if your form is using GET it needs to be $_SERVER['GET']
['IngQty'].

I've tried implementing your comments but can't make it work. Below
is all of my code (testing) could you point out my mistake because it
is still spitting out a "Warning: Invalid argument supplied for
foreach()" error message.

<body>

<?php
foreach($_SERVER['POST']['IngQty'] as $key => $value) {
echo $key." : ".$value."<br/>";
}

echo "Count: ".count($_SERVER['POST']['IngQty'])."<br/><hr>" ;
?>

<form id="form1" name="form1" method="post" action="">
<p>
<input type="text" name="IngQty[0]"><br>
<input type="text" name="IngQty[1]"><br>
<input type="text" name="IngQty[2]">
</p>
<p>
<input type="submit" name="Submit" value="Submit" />
</p>
</form>

</body>
</html>

Thank you for all your ! Is there a good tutorial you could
recommend or subject name that I should lookup that covers this (I
don't even know what I am trying to do is called).

The first time the script is run the form hasn't been submitted so
$_SERVER['POST']['IngQty'] doesn't even exist. You need to check it
first:

?php
if(isset($_SERVER['POST']['IngQty']) && is_array($_SERVER['POST']
['IngQty'])) {
foreach($_SERVER['POST']['IngQty'] as $key => $value) {
echo $key." : ".$value."<br/>";
}

echo "Count: ".count($_SERVER['POST']['IngQty'])."<br/><hr>" ;
}
?>

I know... I hadn't gotten to cleaning up the code yet. just trying to
get it functional.

I did a copy/paste of your code but still nothing? No error, but no
echo either when submitted.

Also, excuse my ignorance but what is the dif btw $_SERVER['POST']
['...'] and $_POST['...']

Oops, that's what my code should have said: $_POST['IngQty']

Sorry 'bout that.
