[英]Get values from table column if row checked
I am using PHP to get values from the table and need to process them further. 我正在使用PHP从表中获取值,并且需要进一步处理它们。 If row is checked I need to get values from columns Quantity and FMK Code. 如果选中行,则需要从“数量”和“ FMK代码”列中获取值。
Table: 表:
<table class="table table-bordered">
<thead>
<tr class="success">
<th>#<br/></th>
<th>Article </th>
<th>Name </th>
<th>Quantity</th>
<th>FMK CODE<br/></th>
</tr>
</thead>
<tbody>
<?php
$i = 1;
while($r=$q->fetch()){ ?>
<tr>
<td><input type="checkbox" class="from-control" name="id[]" value="<?php echo $r['id']?>"></td>
<td><?=$r['Article']?></td>
<td><?=$r['Name']?></td>
<td><input type="text" class="form-control" value="<?=$r['quantity'];?>" name="quantity"></td>
<td>
<select class="form-control col-lg-2" name="childCode"><?php getChildCodes($r["code"]) ?></select>
</td>
</tr>
<?php } ?>
</tbody>
</table>
On submit I need to get values from "quantity and childCode" for each row selected. 在提交时,我需要从“ quantity and childCode”中为所选的每一行获取值。
<button type="submit" name="getValues"> Submit </button>
PhP processing: PhP处理:
<?php
if (isset($_POST['getValues'])) {
$id = $_POST['id'];
$quantity = $_POST['quantity'];
$childCode = $_POST['childCode'];
$values = array();
foreach($id as $id) {
foreach($quantity as $quant){
foreach($childCode as $code){
array_push($values, $id,$quant,$code);
}
}
echo "<pre>";
var_dump($values);
echo "</pre>";
}
?>
values output. 值输出。 In output I get all values from table, no matter if they are checked or not which is wrong. 在输出中,无论是否检查了值,我都从表中获取所有值,这是错误的。 Also array print was not well, values from one name form array. 同样,数组打印也不好,一个名称的值形成数组。 I need array to be formed first element of id, quantity, child code to b one array. 我需要将数组ID,数量,子代码的第一个元素形成一个数组。 [0]=>"177239","10.000",113 [0] => “177239”, “10.000”,113
array(3) {
[0]=>
array(1) {
[0]=>
array(3) {
[0]=>
string(6) "177239"
[1]=>
string(6) "177240"
[2]=>
string(6) "177241"
}
}
[1]=>
array(3) {
[0]=>
string(6) "10.000"
[1]=>
string(7) "100.000"
[2]=>
string(6) "10.000"
}
[2]=>
array(3) {
[0]=>
string(11) "113"
[1]=>
string(10) "87"
[2]=>
string(10) "91"
}
}
misorude is pointing out that you need to name the form elements in a style that builds a PHP array. misorude指出您需要使用一种构建PHP数组的样式来命名表单元素。 That is done with the []
characters as mentioned. 可以通过上述[]
字符来完成。 So the first row would have element names like <input name="id[0]" ...
, <input name="quantity[0]" ...
. 因此,第一行将具有元素名称,例如<input name="id[0]" ...
, <input name="quantity[0]" ...
The second row would have element names like <input name="id[1]"
and <input name="quantity[1]"
第二行将具有元素名称,例如<input name="id[1]"
和<input name="quantity[1]"
Also make sure the foreach
block doesn't overwrite the $id
variable :) 还要确保foreach
块不会覆盖$id
变量:)
foreach($id as $id) // Oops!
