How to send array by post method
Following is my sample form.
<form METHOD="post" METHOD="post" ACTION="index.php" METHOD="post" METHOD="post" METHOD="post">
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="text" NAME="array[]" />
<input TYPE="submit" NAME="submit" VALUE="Submit" />
</form>
Basically I have 10 inputs of array. Assume my domain is http://domain.com and the file above is index.php. I am trying to fill the form automatically by using the following method.
http://domain.co开发者_运维技巧m/index.php?array[]=John&array[]=Kelly ... & array[]=Steven
Unfortunately, it is not working. :(
Have you tried something like this:
<?php
foreach( $_GET['array'] as $arr ) // Loop through the `array` variables of GET
echo '<input type="text" name="array[]" value="' . $arr . '" />'; // Display the the inputs
?>
However, please make sure that you use a cleaning function on $arr to prevent XSS. You will also need to check if $_GET['array'] is set or not, or PHP will whine about it.
Two things to try.
- You are using the GET method with your example URL, but your form is set to POST. In your PHP, you may be looking for your data in $_POST when it's actually in $_GET. You can get data from both POST and GET using the $_REQUEST variable.
- You may need to urlencode the []. ([] becomes %5B%5D when urlencoded.)
Lastly, a tip: when crafting links to send data through a GET query string, it is best practice to use &
in place of the &'s in the URL.
If you are trying to fill the form from a GET request (your URL string), you have to get the values from the HTTP request in the $_REQUEST array (or $_GET or $_POST depending on the form method). Suggestion: you should change the names of the form fields to reflect the value they are storing
<form METHOD="post" METHOD="post" ACTION="index.php" METHOD="post" METHOD="post" METHOD="post">
<input TYPE="text" NAME="first_name" value="<?php echo $_REQUEST['first_name']?>"/>
Note: accessing the $_REQUEST array as shown above is not good practice as you need to check if the request variables are set before you can echo their values.
<form METHOD="post" METHOD="post" ACTION="index.php" METHOD="post" METHOD="post" METHOD="post">
<input TYPE="text" NAME="first_name" value="<?php echo isset($_REQUEST['first_name'])?$_REQUEST['first_name']:""?>"/>
