我的ajax是
$.ajax({
type: ‘POST’,
url: ajax.ajax,
contentType: false,
processData: false,
dataType: ‘JSON’,
status: 200,
data: formdata,
success: function(msg){
$(‘#success_message’).fadeIn().html(data);
setTimeout(function() {
$(‘#success_message’).fadeOut(“slow”);
}, 2000 );
}
});
这是PHP的一部分
function form(){
global $wpdb;
$table = cars;
foreach ($_FILES as $file) {
if($file[‘error’] == UPLOAD_ERR_NO_FILE) {
continue;
}
$valid_ext = array( ‘img’ , ‘png’);
$extension_upload = strtolower( substr( strrchr($file[‘name’], ‘.’) ,1) );
if ( in_array($extension_upload,$valid_ext) ) {
$name_upload = uniqid() . $file[‘name’];
$url_insert = trailingslashit( plugin_dir_path( dirname( __FILE__ ) ) ) . ‘uploads’;
wp_mkdir_p($url_insert);
$name_insert = trailingslashit($url_insert) . $name_upload;
$action = move_uploaded_file($file[‘tmp_name’],$name_insert);
$data = array( ‘customer_resume’ => $name_upload );
$format = array( ‘%s’ );
$success=$wpdb->insert( $table, $data, $format );
$msg_true = ‘Upload ok ‘;
} else {
$msg_error = ‘Upload error’;
}
}
$result = !isset($msg_error);
$msg = array();
if($result) {
$msg[‘error’] = ‘true’;
$msg[‘true’] = $msg_true;
} else {
$msg[‘error’] = ‘false’;
$msg[‘false’] = $msg_error;
}
header(‘Content-Type: application/json’);
echo json_encode($msg);
}
以及我尝试显示成功或错误消息的HTML
当我单击“提交”按钮时，我一切正常，并保存在数据库中，但是没有任何迹象表明是否成功。我尝试添加此msg，但页面上仍然没有任何显示。
