<?php

while ($rowClass=mysqli_fetch_assoc($rstClass)) {

echo "<option disabled>{$rowClass['name']}</option>";

$sqlBrand = "select * from brand where sort_id='{$rowClass[id]}' ";

$rstBrand = mysqli_query($conn,$sqlBrand);

while ($rowBrand=mysqli_fetch_assoc($rstBrand)) {

echo "<option value='{$rowBrand['id']}'>  |-{$rowBrand['name']}</option>";
}
}
?>
</select>
</li>

</li>

<li>

<input type="submit" value="添加商品">

</form>

</div>

查看数据：

    echo "<pre>";

print_r($_POST);

echo "</pre>";

echo "<pre>";

print_r($_FILES);

echo "</pre>";

exit;

测试如图：



。php文件代码：

<?php

require('../../public/common/config.php');

// echo "<pre>";

// print_r($_POST);

// echo "</pre>";

// echo "<pre>";

// print_r($_FILES);

// echo "</pre>";

// exit;

$name = $_POST['goodsname'];
$price = $_POST['goodsprice'];
$sort = $_POST['goodsort'];
$shelf = $_POST['shelf'];
$brand_id = $_POST['brand_id'];

//图片上传

$src = $_FILES['img']['tmp_name'];

$name = $_FILES['img']['name'];

$ext = array_pop(explode('.', $name));

$dst = '../../public/uploads/'.time().mt_rand().'.'.$ext;

if(move_uploaded_file($src, $dst)){
echo "upload success";

//图片缩放200*200

}else{
echo "upload error";
}

?>
