通过php将复选框中的多值插入数据库

我想将此表单值插入datanase：

<input type="checkbox" name="brand1" id="brand1" value="1"> <label for="brand1">Brand 1</label>
<input type="checkbox" name="brand2" id="brand2" value="1"> <label for="brand2">Brand 2</label>
<input type="checkbox" name="brand3" id="brand3" value="1"> <label for="brand3">Brand 3</label>
<input type="checkbox" name="brand4" id="brand4" value="1"> <label for="brand4">Brand 4</label>
<input type="checkbox" name="brand5" id="brand5" value="1"> <label for="brand5">Brand 5</label>

如果通过if和while编写，但它不起作用，因为if insert在while{}时运行了五次insert Done，if insert在while{}时运行了，$brand=“5，”

感谢您对此问题的帮助或想法

这意味着：

<form method="post" action="#">
<?php
$result = $db->getall(brands);
        if(!empty($result)) {
    while ( list($key,$val)=each($result) ) {
        $brand_id = stripslashes($val["id"]);
        $brand_name = stripslashes($val["name"]);
    ?>
    <input type="checkbox" name="brand<?php print"$brand_id"; ?>" value="1" style="cursor:pointer;"><label for="brand<?php print"$brand_id"; ?>" style="cursor:pointer;"> <?php print"$brand_name"; ?></label>
    <?php }} ?>

您应该将复选框的名称更改为
品牌[]
。一旦在
$\u POST['brand']

Ex. 

<input type="checkbox" name="brand[]" value="1" ... />
<input type="checkbox" name="brand[]" value="2" ... />
<input type="checkbox" name="brand[]" value="3" ... />
<input type="checkbox" name="brand[]" value="4" ... />
<input type="checkbox" name="brand[]" value="5" ... />

在这一点上，你将有逗号分隔形式的品牌
 我认为您应该尝试编辑您的问题并再次解释所有内容，因为很难理解您要如何插入以及您的问题是什么在PHP块之外。
<input type="checkbox" name="brand1" value="1"> <label for="brand1">Brand Name 1</label>
<input type="checkbox" name="brand2" value="1"> <label for="brand2">Brand Name 2</label>
<input type="checkbox" name="brand3" value="1"> <label for="brand3">Brand Name 3</label>
<input type="checkbox" name="brand4" value="1"> <label for="brand4">Brand Name 4</label>
<input type="checkbox" name="brand5" value="1"> <label for="brand5">Brand Name 5</label>
<input type="submit" value="Submit" />
</form>

    <?php
$result = $db->getall(brands);
        if(!empty($result)) {
    while ( list($key,$val)=each($result) ) {
        $brand_id = brand.stripslashes($val["id"]);
        $brand_name = stripslashes($val["name"]);
    $brand_ids = "brand.$brand_id";
    if($$brand_ids==1) {$brands="$brandid,"}

}} ?>
$db->add_submenu("$brands"); 

Ex. 

<input type="checkbox" name="brand[]" value="1" ... />
<input type="checkbox" name="brand[]" value="2" ... />
<input type="checkbox" name="brand[]" value="3" ... />
<input type="checkbox" name="brand[]" value="4" ... />
<input type="checkbox" name="brand[]" value="5" ... />

// this will return '1, 2, 3, 4, 5' when all are selected. 
$index = implode(", ", $_POST['brand']);
