php if statement html option value
Suppose you have the following html select statement
-
Give name to your select.
<select name="selectedValue"> <option value="Newest">Newest</option> <option value="Best Sellers">Best Sellers</option> <option value="Alphabetical">Alphabetical</option> </select>in your PHP, you will do:
$_POST['selectedValue'];if I were you, I would prefer a switch-case incase, there are more than 2 conditions.
Example:
switch($_POST['selectedValue']){ case 'Newest': // do Something for Newest break; case 'Best Sellers': // do Something for Best seller break; case 'Alphabetical': // do Something for Alphabetical break; default: // Something went wrong or form has been tampered. }讨论(0) -
I think the read-friendly version would be:
switch($option){ case 'Newest': runNewestFunction(); break; case 'Best Sellers': runBestSellersFunction(); break; case 'Alphabetical': runAlphabeticalFunction(); break; default: runValidationRequest(); }also, please add the name attribute
<select name="option">讨论(0) -
First put a name on your select:
<select name="demo"> <option value="Newest">Newest</option> <option value="Best Sellers">Best Sellers</option> <option value="Alphabetical">Alphabetical</option> </select>Then
if ($_POST['demo'] === 'Newest') { // Run this } elseif ( $_POST['demo'] === 'Best Sellers' ) { // Run this }or
switch($_POST['demo']){ case 'Newest' : //some code; break; case 'Best Sellers': //some code; break; default: //some code if the post doesn't match anything }讨论(0) -
The
<select>should have anameattribute, e.g<select name="sortorder">. You could then sayif ($_REQUEST['sortorder'] == 'Newest') { // TODO sortorder 'Newest' was selected. }If you know whether the form data is comming in via HTTP GET or HTTP POST, you could use
$_GET['sortorder']or$_POST['sortorder']respectively.讨论(0)
