passing form dynamic values

tunks

I've got this code inside a form:

<td align="center">
<input type="checkbox" name="chk<?php echo $anything; ?>">
</td>
<td align="center"><input type="textbox" name="qty<?php echo $anything; ?>" size="1" value="1">
</td>

Number and Name of checkboxes and textboxes changes (dynamic) according to value of $anything.
How do I pass the values to a php script for doing a loop to
check value of the checkbox?

Is it better to use an array name? How?

Please help.

Thanks in advance. 😕

Hi,

You're better off dynamically creating the array in the form itself like this:

<td align="center">
<input type="checkbox" name="chk[]>">
</td>
<td align="center"><input type="textbox" name="qty[]>" size="1" value="1">
</td>

If you do that, and assuming you're using POST as the form method, adding $chkarray = $POST[chk] and $qtyarray = $POST[qty] to your form handling script will give you two arrays containing all the values of chk and qty. You can then step through them pretty simply using a foreach statement e.g.

foreach($chkarray as $thischk)
{
Do interesting stuff
}

Hope this helps,
Simon.

$chkarray = $POST['chk'];
$qtyarray = $POST['qty'];

value of $chkarray and $qtyarray= Array?

foreach($chkarray as $thischk)
{
Do interesting stuff
}
how to corresponse $thischk to $qtyarray

if ($thischk=="on") {
echo $qtyarray;}
doesn't work

Hi,

Yes, $chkarray and $qtyarray will both be arrays. To correlate the two you can loop through them like this:

$numitems = sizeof($qtyarray);
for($i=0; $i<$numitems; $i++)
{
   if ($chkarray[$i] == "ON")
   {
      echo $qtyarray[$i];
   }
}

Best wishes,
Simon.

$numitems = sizeof($qtyarray);
for($i=0; $i<$numitems; $i++)
{
if ($chkarray[$i] == "ON")
{
echo $qtyarray[$i];
}
}

this always return to the record of the first array in the form i.e:
if we checked on the last 4th checkbox on the form
the value of $qtyarray[$i] always be the value of the first record in the form.

how to make $qtyarray[$i] as the value of the checkboxed?

Thanks again.

Do you have a URL for the form so that I can look at it please?

		<td align="center"><input type="textbox"  
				    name="qty[]" 
				    size="1" value="1">
		</td>

		<td align="left">  <input type="hidden" 
			   	    name="city[]" 
				    value="City1">
				   <b>City1</b>
		</td>

		<td align="right"> <input type="hidden"
				    name="price[]"
				    value="100.00">
				    <b>100.00</b>
		</td>

	</tr>
	<tr>			
		<td align="center"><input type="checkbox" 
				    name="chk[]">
		</td>

		<td align="center"><input type="textbox"  
				    name="qty[]" 
				    size="1" value="1">
		</td>

		<td align="left">  <input type="hidden" 
			   	    name="city[]" 
				    value="City2">
				   <b>City2</b>
		</td>

		<td align="right"> <input type="hidden"
				    name="price[]"
				    value="200.00">
				    <b>200.00</b>
		</td>

	</tr>

</form>
</table>

that's the form
haven't publish
$count=sizeof($qtyarray);
for($i=0; $i<$count; $i++)
{
if ($chkarray[$i] == "on")
{
echo $i;
echo "$qtyarray[$i] <br>";
}
}

$i will return the number of checked-checkbox instead of which checkbox has been checked
this code seems to count the number of the checkbox instead of checking which checkbox is clicked

My bad coding, sincere apologies. Make your form like this:

<form action='phpVerifyPurchase.php' method='post' target='Area_4'> 
<hr align="center"> 
<table bgcolor="#ccccff" border="1" align="center"> 
<tr> 
<td align="center"><input type="checkbox" 
name="chk[0]"> 
</td> 

<td align="center"><input type="textbox" 
name="qty[0]" 
size="1" value="1"> 
</td> 

<td align="left"> <input type="hidden" 
name="city[0]" 
value="City1"> 
<b>City1</b> 
</td> 

<td align="right"> <input type="hidden" 
name="price[0]" 
value="100.00"> 
<b>100.00</b> 
</td> 

</tr> 
<tr> 
<td align="center"><input type="checkbox" 
name="chk[1]"> 
</td> 

<td align="center"><input type="textbox" 
name="qty[1]" 
size="1" value="1"> 
</td> 

<td align="left"> <input type="hidden" 
name="city[1]" 
value="City2"> 
<b>City2</b> 
</td> 

<td align="right"> <input type="hidden" 
name="price[1]" 
value="200.00"> 
<b>200.00</b> 
</td> 

</tr> 
<tr><td colspan=4> 
</td></tr> 
<tr><td colspan=4 align='center'> 
<input type='submit' value='SUBMIT'> 
</td></tr> 

</form> 
</table>

And then this code will cycle through properly:

$chkarray = $_POST[chk];
$qtyarray = $_POST[qty];
$numitems = sizeof($qtyarray);
for($i=0; $i<$numitems; $i++)
{
	if ($chkarray[$i] == "ON")
	{
		echo "Checkbox $i = $qtyarray[$i]<BR>";
	}
	else
	{
		echo "Checkbox $i was not checked<BR>";
	}
}

Best wishes,
Simon.
