使用爆破功能读取复选框值 [英] Reading checkbox values using implode function

问题描述

我在此表单中插入了多个复选框项目，这些项目收集了一些值，我需要做的是将此值作为由逗号分隔的字符串进行回显，但是我在implode函数中遇到错误，它表示传递了无效的参数

I have inserted this form with multiple checkbox items which collects some values, What i need to do is echo this values as a string separated by a comma, but i'm getting error in the implode function, it says Invalid arguments passed.

您能看到代码吗?

if(isset($_POST['Submit'])) {
    echo "<pre>"; print_r($_POST);
    $checked = mysql_real_escape_string(implode(',', $_POST['checkbox'])); 
    echo $checked;
}
?>

HTML表单

<form action="checkbox.php" method="post">
<input type="checkbox" name="checkbox[]" value="hostess_name">
<input type="checkbox" name="checkbox[]" value="hostess_familyname_en">
<input type="checkbox" name="checkbox[]" value="hostess_id">
<input type="checkbox" name="checkbox[]" value="hostess_firstname_en">
<br>
<br>
<input type="submit" name="Submit" value="Submit">
</form>

推荐答案

尝试一下

if(isset($_POST['Submit'])) {
    echo "<pre>"; print_r($_POST);
    $checked = implode(',', $_POST['checkbox']); 
    echo $checked;
}

这是我放入test.php

<?php
if(isset($_POST['Submit'])) {
    echo "<pre>";
    $checked = implode(',', $_POST['checkbox']);
    echo $checked;
}

?>
<form action="test.php" method="post">
<input type="checkbox" name="checkbox[]" value="hostess_name">
<input type="checkbox" name="checkbox[]" value="hostess_familyname_en">
<input type="checkbox" name="checkbox[]" value="hostess_id">
<input type="checkbox" name="checkbox[]" value="hostess_firstname_en">
<br>
<br>
<input type="submit" name="Submit" value="Submit">
</form>
