表格代码
table code
<?php
$de=$_POST['text123'];
echo $de;
?>
<body>
<form action="kl2.php" method="post" >
<table border="1" align="center" id="wr123">
<tr>
<th>WAS</th>
<th>NO.</th>
<th>AVERAGE</th>
<th>APPROX</th>
</tr>
<?php
for ($i = 1; $i <= $de; $i++) {
?>
<tr>
<td>Tube</td>
<td>
<select id="in4-<?php echo $i; ?>" name="t1" onclick="getText3(<?php echo $i; ?>)" >
<option value="0">0</option>
<option value="12">12</option>
<option value="18">18</option>
<option value="24">24</option>
<option value="75">75</option>
</select>
</td>
<td>
<input type="text" name="t2" id="in1-<?php echo $i; ?>" onblur="getText3(<?php echo $i; ?>)" />
</td>
<td>
<select name="a1" id="in2-<?php echo $i; ?>" onclick="getText3(<?php echo $i; ?>)" >
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
</select>
</td>
<td>
<input type="text" id="in3-<?php echo $i; ?>" name="username" readonly="readonly" />
</td>
<td>
</tr>
<?php } ?>
<input type="submit" name="submit" />
</table>
</form>
kl2.php
<?php
@$a=$_POST['t1'];
echo @$a;
$sl = $_POST['t2'];
echo $sl;
$b=$_POST['a1'];
echo $b;
$c=$_POST['username'];
echo $c;
?>
在提交时点击它只显示最后一行值，即如果用户输入3，3行后显示点击仅提交最后一行显示的数据
on submit click it only display the last row values i.e if user enter 3 ,3 rows get displayed after clicking the submit only the data of last row display
推荐答案
您需要传递一个数组，您可以将其作为数组在PHP端。
You need to be passing an array, you can deal with it as an array in the PHP side.
为此，在每个输入中，将name =X更改为name =X []
To do this, in each input, change the name="X" to name="X[]"
Example:
<input type="text" name="t2" id="in1-<?php echo $i; ?>" onblur="getText3(<?php echo $i; ?>)" />
到：
<input type="text" name="t2[<?php echo $i; ?>]" id="in1-<?php echo $i; ?>" onblur="getText3(<?php echo $i; ?>)" />
另外，在php中使用@来抑制错误通常是个坏主意。
Also, it's generally a bad idea to use @'s in php to suppress errors.
试试类似：
Try something like:
var_dump($_POST);
，您将看到数据如何传递给您。
and you will see how the data comes through to you.
提示：
Hint:
if (isset($_POST['t1']) {
$t1_data = $_POST['t1'];
}
**编辑**
试试这样：
Try something like this:
<?php
if (isset($_POST['submit'])) {
$data_t1 = $_POST['t1'];
foreach ($data_t1 as $key => $value) {
echo 'T1: ' . $value . '<br />';
echo 'T2: ' . $_POST['t2'][$key] . '<br />';
echo 'Username: ' . $_POST['username'][$key] . '<br /><br />';
}
}
?>
