I want to be able to use a variable (which is a value that is imputed in a textbox) in an Associative Multidimensional Array and print out the rest of the array values associated with it.
here is what i have so far that doesnt work
<html>
<body>
<form method="post" action="newcal.php">
<table>
<tr>
<td> Item #: </td>
<td> <input type=text name= txtitem > <br> </td>
<td>
</td>
<td> <fieldset style = "width:60px">
<input type=submit value = "Get Data" name= getdata>
<input type=submit value = "Add to Cart" name= addto>
<input type=submit value = "Get Total" name= gettotal>
</fieldset>
</td>
</tr>
</table>
</form>
<?php
$item = isset($_POST['txtitem']);
$stuff = array(
array("id" => 1,"name" => "Apples","price" => 50 ),
array("id" => 2,"name" => "Pineapples","price" => 125 ),
array("id" => 3,"name" => "Mango","price" => 35 ),
array("id" => 4,"name" => "Banana","price" => 25 ),
array("id" => 5,"name" => "Naseberry","price" => 38 ));
if(isset($_POST['getdata']))
{
foreach ($stuff as $row)
{
if ($row['id'] == $item)
{
$name = $row['name'];
$price = $row['price'];
}
}
echo $name;
echo $price;
}
?>
</body>
</html>
I think your error is with the following line:
$item = isset($_POST['txtitem']);
$item is being set to a boolean value. You probably want something like this:
$item = (isset($_POST['txtitem']) ? intval($_POST['txtitem']) : null);
