我正在尝试从一个表单中检索post值,其中元素名称基于记录集中的值。这是表格:
$recordID = $_GET["recordID"];
$colour_result = mysqli_query($con,"SELECT colour_variation.*, colours.* FROM colour_variation INNER JOIN colours ON colour_variation.colour_id=colours.colour_id WHERE product_code='$recordID'");
while($colour_row = mysqli_fetch_array($colour_result))
{
?>
<tr><td valign="middle"><img src="resources/images/colours/<?php echo $colour_row['colour_image']; ?>" width="35" height="35"></td><td width="100"><?php echo $colour_row['colour_name']; ?></td>
<td><center><?php if($colour_row['xs'] !== '') { echo('<input type="text" size="2" name="xs_<?php echo $colour_row[colour_name]; ?>" id="xs_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['s'] !== '') { echo('<input type="text" size="2" name="s_<?php echo $colour_row[colour_name]; ?>" id="s_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['m'] !== '') { echo('<input type="text" size="2" name="m_<?php echo $colour_row[colour_name]; ?>" id="m_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['l'] !== '') { echo('<input type="text" size="2" name="l_<?php echo $colour_row[colour_name]; ?>" id="l_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['xl'] !== '') { echo('<input type="text" size="2" name="xl_<?php echo $colour_row[colour_name]; ?>" id="xl_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['xxl'] !== '') { echo('<input type="text" size="2" name="xxl_<?php echo $colour_row[colour_name]; ?>" id="xxl_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['xxxl'] !== '') { echo('<input type="text" size="2" name="xxxl_<?php echo $colour_row[colour_name]; ?>" id="xxxl_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
<td><center><?php if($colour_row['one_size'] !== '') { echo('<input type="text" size="2" name="one_size_<?php echo $colour_row[colour_name]; ?>" id="one_size_<?php echo $row[colour_name]; ?>" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
</tr>
<?php } ?>
</table>
<input type="hidden" name="product_code" value="<?php echo $row_products['product_code']; ?>" >
我试过这个让它们出来但它不起作用:
<?php
$product_code=$_POST["product_code"];
foreach ($_POST as $key => $value) {
if (substr($key, 0, 2) == "xs_") {
$colour_name[str_replace("xs_", "", $key)] = $value;
}
echo $key;
echo '<br />';
echo $value;
}
?>
每种产品可以有任意数量的颜色。任何有关使用每种颜色/尺寸选择数量来显示下一页的值的帮助都将非常受欢迎。
感谢

首先我会改变
name="s_<?php echo $colour_row[colour_name]; ?>"
等
name="attributes[s_<?php echo $colour_row[colour_name]; ?>]"
并使用以下PHP
if( !empty($_POST['attributes']) ) {
foreach( $_POST['attributes'] as $sKey => $iQty ) {
var_dump( $sKey );
var_dump( $iQty );
}
} else {
die( 'Just for debuging. attributes-array was empty' );
}
甚至更好
使用
name="attributes[xxl][color]" eg. name="attributes[xxl][<?php echo $colour_row[colour_name]; ?>]"
和
if( !empty($_POST['attributes']) ) {
foreach( $_POST['attributes'] as $sSize => $aData ) {
var_dump( $sSize );
var_dump( $aData );
}
}
答案 1 :(得分:0)
您将PHP代码放在一个字符串中,它不会被PHP解析:
echo '<input name="xs_<?php echo $colour_row[colour_name]; ?>">';
这应该像这样连接:
echo '<input name="xs_' . $colour_row[colour_name] . '">';
同样如此
echo '<input id="xs_<?php echo $row[colour_name]; ?>">';
需要转换为:
echo '<input id="xs_' . $row[colour_name] . '">';
输入字段的id属性中“$ row”可能必须是“$ colour_row”吗?
还有一些其他明显的改进,但这些改进超出了你的问题范围。
我正在关闭我的Netbeans并发现它仍然坐在那里,我希望它有用(不是100%保证可以开箱即用):
表单php将成为:
<?php
$recordID = $_GET["recordID"];
// I adjusted the query somewhat.
// The colours tabel is joined with a USING() command
// The recordId is escaped
$colour_result = mysqli_query($con, "
SELECT colour_variation.*, colours.*
FROM colour_variation INNER JOIN colours USING(colour_id)
WHERE product_code = '". mysqli_escape_string($con, $recordID)."'
");
// I'm using an alternative syntax for the while control structure ( I am
// using a colon instead of braces ):
while ($colour_row = mysqli_fetch_array($colour_result)): ?>
<tr>
<td valign="middle"><img src="resources/images/colours/<?php echo $colour_row['colour_image']; ?>" width="35" height="35"></td>
<td width="100"><?php echo $colour_row['colour_name']; ?></td>
<!-- I'm using an alternative syntax for the if control structures here -->
<!-- I also left out the else, since it did not print anything -->
<!-- I used an array for the name notation, to easily read out the data -->
<td><center><?php if ($colour_row['xs'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][xs]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['s'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][s]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['m'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][m]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['l'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][l]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['xl'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][xl]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['xxl'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][xxl]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['xxxl'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][xxxl]" placeholder="Qty"><?php endif; ?> </center></td>
<td><center><?php if ($colour_row['one_size'] !== ''): ?><input type="text" size="2" name="quantity[<?php echo $colour_row['colour_name']; ?>][one_size]" placeholder="Qty"><?php endif; ?> </center></td>
</tr>
<?php endwhile; ?>
</table>
<input type="hidden" name="product_code" value="<?php echo $colour_row_products['product_code']; ?>" >
接收端将是这样的:
<?php
$iProductCode = $_POST['product_code'];
foreach($_POST['quantity'] as $sColor => $aColourQuantityData) {
foreach($aColourQuantityData as $sSize => $iQuantity) {
echo "Product #$iProductCode, colour $sColor, size $sSize: $iQuantity pieces<br>";
}
}
?>

好的,我现在使用以下代码在第二页上显示为列表:
<td><center><?php if($colour_row['xxl'] !== '') { echo('<input type="text" size="2" name="xxl_' . $colour_row['colour_name'] . '" placeholder="Qty">');
} else { echo(''); } ?> </center></td>
然后:
<?php
$product_code=$_POST["product_code"];
foreach($_POST as $key=>$value)
{
echo "$key=$value";
echo "<br />";
}
?>
在第二页。
谢谢大家的帮助,你的建议让我走上正轨,非常感谢。
