POProblem with CURL posting data
text
Body
copied!<p>I'll keep this nice and short.</p> <p>I'm trying to post a value to a remote form.</p> <p><strong>This code is working perfectly:</strong></p> <pre><code>$url = "http://eirestudio.net/blog/"; // URL to POST FORM. $post_fields = "s=test"; $ch = curl_init(); // Initialize a CURL session. curl_setopt($ch, CURLOPT_URL, $url); // Pass URL as parameter. curl_setopt($ch, CURLOPT_POST, 1); // use this option to Post a form curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields); // Pass form Fields. curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Return Page contents. $result = curl_exec($ch); // grab URL and pass it to the variable. curl_close($ch); // close curl resource, and free up system resources. echo $result; // Print page contents. </code></pre> <p><strong>But when I test it out on another domain it fails:</strong></p> <pre><code>$url = "http://jobbank.fas.ie/servlet/Watis?SESS=50306_1&TEMPLATE=WWW_JS_VAC_TEXTSEARCH.HTM&BACK=TEMPLATE%3DWWW_JS_VAC.HTM"; // URL to POST FORM. $post_fields = "TEXTSEARCH.JOBNAME=$search"; // $ch = curl_init(); // Initialize a CURL session. curl_setopt($ch, CURLOPT_URL, $url); // Pass URL as parameter. curl_setopt($ch, CURLOPT_POST, 1); // use this option to Post a form curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields); // Pass form Fields. curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // Return Page contents. $result = curl_exec($ch); // grab URL and pass it to the variable. curl_close($ch); // close curl resource, and free up system resources. echo $result; // Print page contents. </code></pre> <p>Can you spot anything wrong with the second piece of code?</p> <p><strong><em>UPDATE: Here is an example: <a href="http://www.keithdonegan.com/labs/" rel="nofollow noreferrer">http://www.keithdonegan.com/labs/</a></em></strong></p> <p><strong>UPDATE 2: Live HTTP Headers</strong> </p> <p><a href="http://www.keithdonegan.com/labs/process.php" rel="nofollow noreferrer">http://www.keithdonegan.com/labs/process.php</a></p> <pre><code>POST /labs/process.php HTTP/1.1 Host: www.keithdonegan.com User-Agent: Mozilla/5.0 (Windows;
