Php 多个复选框插入

以下是包含多个复选框选项和文本区域输入的简单表单：

    <form method="post" name="form1" action="<?php echo $editFormAction; ?>">
    <table>
    <tr><th colspan="2">BREATHING CIRCULATION</th></tr>
    <tr><th>#</th><th>Instruction Name</th></tr>
    <tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Respirations normal rate"></td><td>Respirations normal rate</td></tr>
    <tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Respirations effort normal"></td><td>Respirations effort normal</td></tr>
<tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Breath Sounds-normal"></td><td>Breath Sounds-normal</td></tr>
    <tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Skin colour-normal"></td><td>Skin colour-normal</td></tr>
    <tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="Heart rhythm & rate normal"></td><td>Heart rhythm & rate normal </td></tr>
    <tr><td><input name="InstrCheck[]" type="checkbox" id="InstrCheck" value="No Oedema"></td><td>No Oedema </td></tr>
    </table>
    <textarea name="InstrCheck[]" id="InstrCheck" placeholder="set your own instruction">                          </textarea>
<input type="hidden" name="MM_insert" value="form1">
<input type="hidden" value="<?php echo $_GET['a'];?>" name="pat_id">
</form>

如果我没弄错的话：

IF(isset($_POST['InstrCheck']) && isset($_POST['comment'])) {
    $checked = $_POST['InstrCheck'];
    $comment= $_POST['comment'];
    IF(!empty($checked) && is_array($checked)) {
        foreach($checked as $check) {
            $query = 'INSERT INTO table (checkedID, comment) VALUES (\''.mysql_real_escape_string($check).'\', \''.mysql_real_escape_string($comment).'\'';
            mysql_query($query);
        }
    }
}

您可以根据自己的首选项编辑查询，这只是将多行插入数据库的一种快速方法。

编辑：我误读了您的第一个HTML表单，您应该将文本区域的名称编辑为其他内容，然后选择

InstrCheck[]

，并将其改为

注释

，然后您可以使用上面给出的示例。

您可以使用此HTML表单

<form method="post" name="form1" action="<?php echo $editFormAction; ?>">
    <table>
        <thead>
            <tr><th colspan="2">BREATHING CIRCULATION</th></tr>
            <tr><th>#</th><th>Instruction Name</th></tr>
        </thead>
        <tbody>
            <tr><td><input name="InstrCheck0" type="checkbox" id="InstrCheck0" value="Respirations normal rate" /></td><td>Respirations normal rate</td></tr>
            <tr><td><input name="InstrCheck1" type="checkbox" id="InstrCheck1" value="Respirations effort normal" /></td><td>Respirations effort normal</td></tr>
            <tr><td><input name="InstrCheck2" type="checkbox" id="InstrCheck2" value="Breath Sounds-normal" /></td><td>Breath Sounds-normal</td></tr>
            <tr><td><input name="InstrCheck3" type="checkbox" id="InstrCheck3" value="Skin colour-normal" /></td><td>Skin colour-normal</td></tr>
            <tr><td><input name="InstrCheck4" type="checkbox" id="InstrCheck4" value="Heart rhythm & rate normal" /></td><td>Heart rhythm & rate normal </td></tr>
            <tr><td><input name="InstrCheck5" type="checkbox" id="InstrCheck5" value="No Oedema" /></td><td>No Oedema </td></tr>
        </tbody>
    </table>
    <textarea name="InstrCheck6" id="InstrCheck6" placeholder="set your own instruction"></textarea>
    <input type="hidden" name="MM_insert" value="form1" />
    <input type="hidden" name="pat_id" value="<?php echo $_GET['a']; ?>" />
</form>

保存到数据库中的空单元格是
文本区域中的值

代码只保存
textarea
的原因是因为它是由
mysql\u query
执行的唯一查询。您的
foreach
循环正在覆盖每个查询，
$insertSQL
的最后一个值是textarea查询。因此，要修复此问题，必须在
foreach
循环中移动
mysql\u查询
，并在循环开始之前连接到数据库

/** 
 *  Moving the mysql_query inside the loop requires you connect to the database 
 *  before the loop starts
 */
mysql_select_db($database_PPS, $PPS);

/** Move your mysql_query inside your foreach loop **/
foreach ($_POST['InstrCheck'] as $value) {
    $insertSQL = "INSERT INTO instruction (instName, instTime, instDate, pat_id) VALUES ('$value', '$Time', '$Date', '$pat_id')";

    // Moved inside the loop...now this will run for each loop
    $Result1 = mysql_query($insertSQL, $PPS) or die(mysql_error());

}

其他答案同样好，并指出了一些值得考虑的问题。我只想让您了解原始代码出错的原因。
您是否能够向数据库中写入至少一个选中值？否，检查数据库上的表时，没有错误消息出现。我发现空单元格，但插入了另一个值。我完全按照您在这里所做的操作，在Dreamweaver或db中都没有收到任何错误消息，但根本没有插入任何内容，我想知道输入丢失在哪里？？？尝试添加echo mysql_error（）；在mysql_查询语句之后，看看SQL是否有问题。我需要将它们全部插入同一列（选中选项和文本输入）
<?php

    $Date = date("d-m-Y");
    $Time = date("H:i:s");
    //    Has the form been sent?
    if (isset($_POST["MM_insert"])) {
        //    We can't test what's in $_POST["MM_insert"] before we even know it exists
        if ($_POST["MM_insert"] == "form1")
        {
            //    ONE connection to the database is enough; it shouldn't be in a for or foreach loop
            mysql_select_db($database_PPS, $PPS);
            //    The pattern's id is stored in the pat_id hidden field, right?
            $pat_id = $_POST["pat_id"];
            //    Never trust user input!
            $pat_id = mysql_real_escape_string($pat_id);

            //    Checkboxes & textarea have name attributes going from 0 to 6 (see HTML code)
            for ($i = 0 ; $i < 7 ; $i++)
            {
                //    Is the number $i checkbox checked?
                if (isset($_POST["InstrCheck$i"]))
                {
                    //    Let's get its value
                    $value = $_POST["InstrCheck$i"];
                    //    Again... never trust user input.
                    $value = mysql_real_escape_string($value);
                    //    Insert data
                    mysql_query("
                        INSERT INTO instruction (instName, instTime, instDate, pat_id)
                        VALUES ('$value', '$Time', '$Date', '$pat_id')
                    ");
                }
            }
        }
    }

?>

/** 
 *  Moving the mysql_query inside the loop requires you connect to the database 
 *  before the loop starts
 */
mysql_select_db($database_PPS, $PPS);

/** Move your mysql_query inside your foreach loop **/
foreach ($_POST['InstrCheck'] as $value) {
