Question

我正在使用表单，我有三个提交按钮。编辑，删除和重置但删除和重置按钮不起作用。

我做错了吗？

echo '<form action="" method="post">
   <input type="text" name="login" value="'.htmlspecialchars($object['login']).'" placeholder="Login" /><input type="text" name="password" value="'.htmlspecialchars($object['password']).'" placeholder="Password" />
        <input type="submit" value="Edit" />
        <input type="hidden" name="action" value="edit" />
        <input type="hidden" name="id" value="'.$object['id'].'" />
        <input type="submit" value="Delete" />
        <input type="hidden" name="action" value="dell" />
        <input type="submit" value="Reset" />
        <input type="hidden" name="action" value="res" />
</form>;

在PHP中它看起来像

if($_POST){
$action=(string)$_POST['action'];
$id=(int)$_POST['id'];
$name=(string)$_POST['name'];

$name=trim($_POST['name']);
$name=htmlspecialchars($name,ENT_QUOTES);

    if($action=='add' && $name){
    mysql_query("INSERT INTO `stages` SET
    `name`='".mysql_real_escape_string($name)."'");
    } else if($action=='edit' && $name){
    mysql_query("UPDATE `stages` SET
    `name`='".mysql_real_escape_string($name)."'
    WHERE `id`='".$id."' LIMIT 1");
    } else if($action=='edit'){
                mysql_query("DELETE FROM `stages` WHERE `id`='".$id."' LIMIT 1");
    mysql_query("DELETE FROM `questions` WHERE `stage_id`='".$id."'");
    } else if($action=='dell'){
    mysql_query("DELETE FROM `stages` WHERE `id`='".$id."' LIMIT 1");
    mysql_query("DELETE FROM `questions` WHERE `stage_id`='".$id."'");
    } else if($action=='reset'){
    mysql_query("UPDATE `stages` SET
    `name`=NULL
    WHERE `id`='".$id."' LIMIT 1");

    } 
}

这可能更像是你需要做的工作 - 尽管它没有经过测试。

<?php 
echo '
<form id="actions" action="" method="post">
    <input type="text" name="login" value="'.htmlspecialchars( $object['login'] ).'" placeholder="Login" />
    <input type="text" name="password" value="'.htmlspecialchars( $object['password'] ).'" placeholder="Password" />

    <input type="button" value="Edit" data-action="edit" />
    <input type="button" value="Delete" data-action="dell" />
    <input type="button" value="Reset" data-action="res" />

    <input type="hidden" id="id" name="id" value="'.$object['id'].'" />
    <input type="hidden" id="action" name="action" />
</form>

<script type="text/javascript">
    var col=document.getElementById("actions").querySelectorAll("input[type=\'button\']");
    if( col ){
        for( var n in col )if( n && col[n] && col[n].nodeType==1 ) col[n].addEventListener( \'click\', function(e){
            document.getElementById("action").value=this.dataset.action;
            this.parentNode.submit();
        }.bind( col[n] ),false );
    }
</script>';


    if( $_POST ){
        $action=(string)$_POST['action'];
        $id=(int)$_POST['id'];
        $name=(string)$_POST['name'];

        $name=trim($_POST['name']);
        $name=htmlspecialchars($name,ENT_QUOTES);

        if( $action=='add' && $name ){
            mysql_query("INSERT INTO `stages` SET `name`='".mysql_real_escape_string($name)."'");
        } else if( $action=='edit' && $name ){
            mysql_query("UPDATE `stages` SET `name`='".mysql_real_escape_string($name)."' WHERE `id`='".$id."' LIMIT 1");
        } else if( $action=='edit' ){
            mysql_query("DELETE FROM `stages` WHERE `id`='".$id."' LIMIT 1");
            mysql_query("DELETE FROM `questions` WHERE `stage_id`='".$id."'");
        } else if( $action=='dell' ){
            mysql_query("DELETE FROM `stages` WHERE `id`='".$id."' LIMIT 1");
            mysql_query("DELETE FROM `questions` WHERE `stage_id`='".$id."'");
        } else if( $action=='reset' ){
            mysql_query("UPDATE `stages` SET `name`=NULL WHERE `id`='".$id."' LIMIT 1");
        } 
    }

?>

按钮将调用javascript函数，然后使用适当的操作和其他参数提交表单。
