来自具有相同名称的文本框的PHP请求名称

问题描述：

I have multiple textbox with same name, example :

<input type = "text" name = "addCart"/> 
<input type = "text" name = "addCart"/>
<input type = "text" name = "addCart"/>
<input type = "text" name = "addCart"/>

If I do a $_Request from php and I want to get the value inputted only from the first and fourth textbox, how can I do it? Thanks

答

You can't. The last input box's value will overwrite all of the other ones' since they have the same name.

What you could consider doing is using name="addCart[]"

Then, $_REQUEST['addCart'] would be an array.

Like:

<input type="text" name="addCart[]" value="a">
<input type="text" name="addCart[]" value="b">

Then $_REQUEST['addCart'] (or $_POST or $_GET whichever you're using) would contain an array of two strings 'a' and 'b'.

Edit: Just for completeness, I should note that this array is a normal array. Thus $_REQUEST['addCart'][x] where x is some integer index is valid as long as count($_REQUEST['addCart']) > x.

<input type = "text" name = "addCart[]"/> 
<input type = "text" name = "addCart[]"/>
<input type = "text" name = "addCart[]"/>
<input type = "text" name = "addCart[]"/>

Access using:

$_REQUEST['addCart'][0]
...
$_REQUEST['addCart'][3]

I don't believe this is possible. try to use slightly different names such as name1, name2 etc

答

try this, this will post the array of addCart. With $_REQUEST you can acces teh first and fourth texhbox by addCart id

<input type = "text" name = "addCart[]"/> 
<input type = "text" name = "addCart[]"/>
<input type = "text" name = "addCart[]"/>
<input type = "text" name = "addCart[]"/>


<?php
echo $_REQUEST['addCart'][0];
echo $_REQUEST['addCart'][3];

?>

答

If you want to use names of that style when using PHP, then you have to bypass $_POST or $_GET, get the raw data and parse it yourself.

For GET requests, then means looking at $_SERVER['REQUEST_URI'] and for POST at file_get_contents('php://input');

If you rename the fields so the names end in [] then they will be presented as an array.

i.e.

<input type = "text" name = "addCart[]"/>

Will be presented as

$_GET['addCart'][] or $_POST['addCart'][]
