Form input options.

[zavin]

I have a form listed below that you can currently select 1 of 3 values. I want to be able to use all 3 values at once. Once the submit button is hit the form need to ad the total of the 3 values to verify that it is greater than 0 and less than $value_ available. I also need the 3 values submitted  separately so they can e inserted into their respective data bases. I sure I'm just over thinking the solution. Any help would be appreciated.

 

<form method='post'>
You can currently use <?php echo $value_available; ?> value.
<input type='text' name='energy' value='0' size='5' maxlength='5'>
<select name='type'>
	<option value='1'>Value 1</option>
	<option value='2'>Value 2</option>
	<option value='3'>Value 3</option>
</select>
<input type='submit' name='value' value='Use Value'>
</form>

Hello,

 

Below is the solution.. .. That was a simple stuff i believe.. ... you should have tried this assignment...Hope u get good marks...

 

<?php
$value_available = 5;
?>
<form method='post'>
   You can currently use <?php echo $value_available; ?> value.
   <input type='text' name='energy' value='0' size='5' maxlength='5'>
   <select name='type[]' multiple="true">
      <option value='1'>Value 1</option>
      <option value='2'>Value 2</option>
      <option value='3'>Value 3</option>
   </select>
<input type='submit' name='value' value='Use Value'>
</form>

<?PHP
if(!empty($_POST)){
if(!empty($_POST['type'])){
	$posted_val = $_POST['type'];
	$total = 0;
	foreach($posted_val as $key=>$val){
		$total = $total + $val;
	}	
	if($total > 0 && $total < $value_available){
		echo "Success";
	}else{
		echo "Fail";
	}
	// THREE SUBMITTED VALUES CAN BE FIND IN $_POST['type'] array
}
}
