这是设置：

<form method="post" action="">
    <input type="hidden" name="delete_app_id" id="delete_app_id" value=\'<?php 
        echo $adoptee->app_id; ?>\' />
    <input type="submit" name="delete" value="delete" />
</form>
<?php

if ( isset( $_POST[\'delete\'] ) ) {
    $delete_id=$_POST[\'delete_app_id\'];
    $adoptees_delete=$wpdb->query( "DELETE 
        FROM $wpdb->rc_vol_adopt_apps 
        WHERE app_id =\'$delete_id\'" );
    if ( $adoptees_delete ) {
        echo \'Record Deleted\';
    } else{
        echo \'Have a ham sandwich - cause this FAILED\';
    }
}

它不会跑的！它正在收集delete_app_id 以及delete 从提交后开始，但之后什么都没有发生。好像看不到if isset 陈述我错过了什么？

$wpdb->query($wpdb->prepare("DELETE FROM $wpdb->rc_vol_adopt_apps WHERE app_id = %d",$delete_id));
