用户可以从复选框中进行选择。我想通过 jquery 将复选框作为数组获取，然后通过 ajax 传递给 php。似乎我无法获得数组和进程。我在 SO 上看到过其他答案，但似乎都没有。
HTML/PHP
<?php foreach ( $results['buckets'] as $bucket ) { ?>
<div><?php echo $bucket->name ?></div>
<input type="checkbox" name="buckets[]" id="<?php echo strtolower( $bucket->name ) ?>" class="buckets" value="<?php echo $bucket->id ?>" style="visibility: hidden" /><label for="<?php echo strtolower( $bucket->name ) ?>" class="<?php echo strtolower( $bucket->name ) ?>"><?php echo $bucket->name ?></label>
<?php } ?>
JS
$( function() {
$( "#form" ).submit( function() {
var buckets = new Array();
$( "input[name='buckets[]']:checked" ).each( function() {
buckets.push( $( this ).val() );
} );
var valid = false;
$.ajax( {
type: "POST",
url: "/scripts/validateBucketSelect.php",
data: buckets,
cache: false,
async: false,
success: function( error ) {
if ( error == "null" ){
valid = true;
} else {
$( ".errorMessage" ).html( error );
}
}
} );
return valid;
} );
} );
PHP
$postData = $_POST;
if ( count( $postData['buckets'] ) < 3 ) {
echo "Oops! You have to select at least 3 buckets.";
} elseif ( count( $postData['buckets'] ) > 5 ) {
echo "Oops! You cannot select more than 5 buckets.";
} else {
echo "null";
}
