JQuery似乎正在设置一个额外的$u POST值

我正在开发一个Wordpress插件。有多个表单元素，出于某种原因，每次我在一个表单上单击submit按钮时，它都会通知另一个表单进行提交。这很不方便，因为当我单击按钮保存新信息时，另一个表单会从数据库中删除第一行

Javascript:

//This is the Javascript that controls the remove all form.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>

<script type="text/javascript">
    $(document).ready(function(){
        $('tr.assoc_row').show();
        $('#settings-removed-msg').hide();
        $('#formdeleteassoc').submit(function(e){
            e.preventDefault(); //Works to prevent normal submission of the form.

            $.ajax ({
                type: 'POST',
                url: '',
                data: {remove_all: ''
                },
                success: function() {
                    $('#settings-removed-msg').fadeIn('fast'); //Working now
                    $('tr.assoc_row').fadeOut('fast'); //Working now
                    }
            });

        });
    });
</script>

//这是控制remove all表单的Javascript。
$（文档）.ready（函数（）{
$（'tr.assoc_row'）.show（）；
$（“#设置已删除消息”）.hide（）；
$（'#formdeleteassoc'）。提交（函数（e）{
e、 preventDefault（）；//用于阻止表单的正常提交。
$.ajax({
键入：“POST”，
url:“”，
数据：{全部删除：“”
},
成功：函数（）{
$（“#设置已删除msg”）.fadeIn（'fast'）；//正在工作
$（'tr.assoc_row'）.fadeOut（'fast'）；//正在工作
}
});
});
});

HTML

<!-- This the the HTML and PHP that renders the options page in Wordpress. -->
<div class="wrap">
    <?php screen_icon('plugins'); ?>
    <h2>Tag to Category Associator</h2>
    <div id="settings-removed-msg" class="updated"><p>Associations were successfully removed.</p></div>
    <form action="<?php echo $_SERVER['PHP_SELF'].'?page=tag2cat-associator'; ?>" method="post">


    <?php
    settings_fields('cb_t2c_options');
    do_settings_sections('tag2cat-associator');
    ?>

    <input name="Submit" type="submit" value="Save Changes" />
    </form></div>

问题是由于在Wordpress中有两个设置字段作为注册设置。基本结构是：

function cb_t2c_admin_init() {
register_setting('cb_t2c_options', 'cb_t2c_options' /*'cv_t2c_validate_options'*/);

    //Define sections and settings
    add_settings_section(
        //This defined the settings section.
        );

    add_settings_field(
        //This defined the first setting, with a call to a function.
        );

    add_settings_field(
        //This defined the unwanted setting.
    );

}

我想用Wordpress实现的是在表单之外有一个部分，它将在一个简单的HTML表中向用户显示当前选择的选项。因此，我删除了第二个“add_settings_field”函数，获取其回调函数的内容，并将其放在绘制选项页面的函数末尾。例如：

//Draw the options page
function cb_t2c_plugin_options_page () {
    $cb_t2c_remove_all_url = plugin_dir_url( _FILE_ ) . 'remove_all.php';
?>

    <div class="wrap">
    <?php screen_icon('plugins'); ?>
    <h2>Title</h2>
    <div id="new-assoc-msg" class="updated"><p>Data was successfully added.</p></div>
    <form id="formsavesettings" name="save_settings" action="<?php echo $_SERVER['PHP_SELF'].'?page=the_options_page'; ?>" method="post">

    <?php
    settings_fields('cb_t2c_options');
    do_settings_sections('section_name');
    ?>

    <input name="Submit" type="submit" value="Save Changes" />
    </form></div>
    <?php

// Here is where I added the PHP code to show my table full of already selected values.
// This is accomplished with 1 settings section and 1 settings field.
// By previously putting the code in a settings field, I was telling Wordpress to pass along the values to the form.
};

//绘制选项页
功能cb_t2c_插件_选项_页面（）{
$cb_t2c_remove_all_url=plugin_dir_url（_FILE_）。'remove_all.php'；
?>

您有SQL注入漏洞。能否更清楚地指定问题？每次单击时，都会设置$\u REQUEST['remove\u single']，并最终从表中删除一行。如果这是由于SQL注入漏洞造成的，我如何修复它？谢谢。
//Draw the options page
function cb_t2c_plugin_options_page () {
    $cb_t2c_remove_all_url = plugin_dir_url( _FILE_ ) . 'remove_all.php';
?>

    <div class="wrap">
    <?php screen_icon('plugins'); ?>
    <h2>Title</h2>
    <div id="new-assoc-msg" class="updated"><p>Data was successfully added.</p></div>
    <form id="formsavesettings" name="save_settings" action="<?php echo $_SERVER['PHP_SELF'].'?page=the_options_page'; ?>" method="post">

    <?php
    settings_fields('cb_t2c_options');
    do_settings_sections('section_name');
    ?>

    <input name="Submit" type="submit" value="Save Changes" />
    </form></div>
    <?php

// Here is where I added the PHP code to show my table full of already selected values.
