我是php mysql的初学者,我有一个问题,如下图片类型的表单如何保存所有行的值或只选择行字段值: - 字段名称如下: -
foreach($data as $row){
<tr>
<td><input type="checkbox" value="$row['ProductID']" name="productID[]" /></td>
<td> <input type="text" value="$row['Quantity']" name="quantity[]" /></td>
<td><input type="text" value="$row['Price']" name="price[]" /></td>
</tr>
}
1。问题是如何在php或jquery 中仅获取选定的行字段值 我不知道如何只在php中选择行字段值

如果您试图获取所有项目的列表,无论是否选择了注释,只需更改您的表单名称(如果我理解您要查找的内容......):
<?php
$data[] = array('ProductID'=>123,"Quantity"=>1,"Price"=>"2.00");
$data[] = array('ProductID'=>234,"Quantity"=>2,"Price"=>"1.50");
$data[] = array('ProductID'=>345,"Quantity"=>1,"Price"=>"4.59");
$data[] = array('ProductID'=>456,"Quantity"=>4,"Price"=>"1.99");
foreach($data as $row){ ?>
<tr>
<td><input type="checkbox" name="product[<?php echo $row['ProductID'];?>][select]" /></td>
<td><input type="text" value="<?php echo $row['Quantity']; ?>" name="product[<?php echo $row['ProductID'];?>][qty]" /></td>
<td><input type="text" value="<?php echo $row['Price']; ?>" name="product[<?php echo $row['ProductID'];?>][price]" /></td>
</tr>
<?php }
给你:
// Just loop through the [product] array looking for the 'select' = 'on'
Array
(
[product] => Array
(
[123] => Array
(
[qty] => 1
[price] => 2.00
)
[234] => Array
(
[select] => on
[qty] => 2
[price] => 1.50
)
[345] => Array
(
[qty] => 1
[price] => 4.59
)
[456] => Array
(
[qty] => 4
[price] => 1.99
)
)
)
获取所选项目:
if(!empty($_POST['product'])) {
foreach($_POST['product'] as $row) {
if(!empty($row['select'])) {
print_r($row);
}
}
}
