[SOLVED] menu

[DeFActo]

Hello all,

i have a code

echo '<select name="menu">';
echo '<option>Artist</option>';
echo '<option>Song</option>';
echo '</select>';

could someone tell me how to do so that if i choose Artist my variable $value gets the value "artists" ?

Thank you in advance.

I guess you are submitting the form when the user chooses an item from the list, if so use $_POST['name'] or $_GET['name'] depending on your forms submit method.

i have tried to use it, but getting error

<form method="post" action="menu.php">
<?php
echo  '<select id="selectElemId" name="selectElem[]">';
echo  '<option value="ham">Ham</option>';
echo  '<option value="cheese">Cheese</option>';
echo  '<option value="hamcheese">Ham and Cheese</option>';
echo  '</select>';
$var=$_GET['selectElem'][];
?>
</form>

It would be $_GET['selectElem'], not $_GET['selectElem'][]

<form method="post" action="menu.php">
<?php
echo  '<select id="selectElemId" name="selectElem[]">';
echo  '<option value="ham">Ham</option>';
echo  '<option value="cheese">Cheese</option>';
echo  '<option value="hamcheese">Ham and Cheese</option>';
echo  '</select>';
$var=$_GET['selectElem'][];
?>
</form>

Is that all your code? If it is there is a few issues:

1. There is no submit button. In order for PHP to retrieve data from the form it needs to be submitted.

2. Your form method is set to post so you'll use the $_POST superglobal instead, eg $_POST['selectElemId']

3. You should always check to see if user defined variables exists first before using them to prevent the "Underfined index notice" notices (these are not errors)

thats what i got

Notice: Undefined index: selectElem in menu.php on line 8

i'd like to do it without submit button.

Then you'll need use a bit of javascript to submit the form once a user has selected an item from the list

<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<select name="selectElem" onChange="this.form.submit()">
<option>Filling</option>
<option value="ham">Ham</option>
<option value="cheese">Cheese</option>
<option value="hamcheese">Ham and Cheese</option>
</select>
</form>

<?php

if(isset($_POST['selectElem']))
{
    echo $_POST['selectElem'];
}

?>
