如何从textarea表单发布数据？

Here is my current code:

<?php
$apikey='IGNORE-THIS-VARIABLE';

// All URLS to be sent are hold in an array for example
$urls=array('http://www.site1.com','http://www.site2.com/');

// build the POST query string and join the URLs array with | (single pipe)
$qstring='apikey='.$apikey.'&urls='.urlencode(implode('|',$urls));

// Do the API Request using CURL functions
$ch = curl_init();
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_URL,'http://www.example.com/api.php');
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_TIMEOUT,40);
curl_setopt($ch,CURLOPT_POSTFIELDS,$qstring);
curl_exec($ch);
curl_close($ch);
?>

My PHP code works, but here's the line I'm having issues with:

$urls=array('http://www.site1.com','http://www.site2.com/');

Basically I just want to have a text-area on my website where users can enter a list of URLs (one per line) and then it Posts it using the PHP code above.

My code works when I just have the URLs built into the code like you can see above, but I just can't figure out how to make it work with a text-area... Any help would be appreciated.

You can do it like below (on the same php page):-

<form method = "POST">

<textarea name="urls"></textarea><!-- add a lable that please enter new line separated urls -->

<input type = "submit">

</form>

<?php

if(isset($_POST['urls'])){
    $apikey='IGNORE-THIS-VARIABLE';

    // All URLS to be sent as new-line separated string  and explode it to an array
    $urls=explode('
',$_POST['urls']); //Or $urls=explode('\
',$_POST['urls']);
    // if not worked then 
    //$urls=explode(PHP_EOL,$_POST['urls']); 

    // build the POST query string and join the URLs array with | (single pipe)
    $qstring='apikey='.$apikey.'&urls='.urlencode(implode('|',$urls));

    // Do the API Request using CURL functions
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_POST,1);
    curl_setopt($ch,CURLOPT_URL,'http://www.example.com/api.php');
    curl_setopt($ch,CURLOPT_HEADER,0);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_TIMEOUT,40);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$qstring);
    curl_exec($ch);
    curl_close($ch);
}
?>

Note:- you can separate the form and logic on two different pages. that's seay i think.

You can use text-area and then you have to then explode by or if not work then explode by PHP_EOL to the initial url string and rest the code is same as above

You can pass to the form value as in bellow box is. any tag in HTML form have name attribute, assign name for any textarea, input or select tag.

<form method="post" name="first_form">
    <input type="text" name="url" value="" />
    <textarea name="note"></textarea>
    <input type="submit" value="Post" />
</form>

In PHP you can the pass the value using two methods, $_GET or $_POST. assign the tag name which you give for the HTML tag ($_POST['note'] or $_POST['url']) and also you can make it like an array $_POST.

<?php
  if(isset($_POST)){

    // display the posted values from the HTML Form
    echo $_POST['note'];
    echo $_POST['url'];

  }
?>

Your Code:

    $apikey='IGNORE-THIS-VARIABLE';

    // All URLS to be sent are hold in an array for example
    $urls=array('http://www.site1.com','http://www.site2.com/');

    // build the POST query string and join the URLs array with | (single pipe)
    $qstring='apikey='.$apikey.'&urls='.urlencode(implode('|',$urls));

    // Do the API Request using CURL functions
    $ch = curl_init();
    curl_setopt($ch,CURLOPT_POST,1);
    curl_setopt($ch,CURLOPT_URL,'http://www.example.com/api.php');
    curl_setopt($ch,CURLOPT_HEADER,0);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch,CURLOPT_TIMEOUT,40);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$qstring);
    curl_exec($ch);
    curl_close($ch);
