使用PHP获取具有相同名称的2个HTML输入标记的值

Question

Suppose I have the following table:

<form  action="bla.php" method=post>
<table class="pv-data">
<tr>
<td><input type="text" name="id" size="2" value=1 /></td>
<td><input type="text" name="longitude" size="7"/></td>
<td><input type="text" name="latitude" size="7"/></td>
</tr>
<tr>
<td><input type="text" name="id" size="2" value=2 /></td>
<td><input type="text" name="longitude" size="7"/></td>
<td><input type="text" name="latitude" size="7"/></td>
</tr>
</table>
<input type="submit" name="submit" value="SUBMIT">
</form>

I want to assign the values in this table to php variables, so in bla.php

if I used $id = $_REQUEST['id']; only the last value is taken because there are two input tags that have the same name.

So can I request the 2 values of these tags having the same name into php?

p.s don't tell me to change the name of the input tags, because the table is bit more complicated than that and it has dynamic add rows: My real code is: http://jsfiddle.net/CchES/9/

When you have repeated names, you have to give them array-style names:

<form  action="bla.php" method=post>
<table class="pv-data">
<tr>
<td><input type="text" name="id[]" size="2" value=1 /></td>
<td><input type="text" name="longitude[]" size="7"/></td>
<td><input type="text" name="latitude[]" size="7"/></td>
</tr>
<tr>
<td><input type="text" name="id[]" size="2" value=2 /></td>
<td><input type="text" name="longitude[]" size="7"/></td>
<td><input type="text" name="latitude[]" size="7"/></td>
</tr>
</table>
<input type="submit" name="submit" value="SUBMIT">
</form>

When you do this, $_POST['id'], $_POST['latitude'], and $_POST['longitude'] will be arrays containing the values.

Your form processing code can then iterate over these:

for ($i = 0; $i < count($_POST['id']); $i++) {
  if (isset($_POST['latitude'][$i], $_POST['longitude'][$i])) { // Make sure both are filled in
    // Do stuff with this row of the form
  }
}
