<h1> Connection Manager POST Transaction</h1>
<p>
To construct a POST transaction using the Connection Manager, you will need to construct a data string as the POST message. The following code example provides a step-by-step approach to creating a simple POST transaction.
</p>
<h3>Source file and dependencies</h3>
<p>Load the YAHOO namespace and connection manager source file:</p>
<pre><textarea name="code" class="JScript" cols="60" rows="1"><script src="yahoo.js"></script>
<script src="connection.js"></script></textarea></pre>
<h3>Assemble the POST message</h3>
<p>Construct an example of key-value string of <em>username = anonymous</em> and <em>userid = 0</em>:</p>
<pre><textarea name="code" class="JScript" cols="60" rows="1">/*
* Remember to encode the key-value string if and when
* the string contains special characters.
*/
var postData = "username=anonymous&userid=0";
</textarea></pre>
<h3>The Callback Object</h3>
<p>Create a callback object to handle the response and pass an array of values to success and failure as the argument.</p>
<pre>
<pre><textarea name="code" class="JScript" cols="60" rows="1">var handleSuccess = function(o){
if(o.responseText !== undefined){
div.innerHTML = "Transaction id: " + o.tId;
div.innerHTML += "HTTP status: " + o.status;
div.innerHTML += "Status code message: " + o.statusText;
div.innerHTML += "&lt;li&gt;HTTP headers: &lt;ul&gt;" + o.getAllResponseHeaders + "&lt;/ul&gt;&lt;/li&gt;";
div.innerHTML += "PHP response: " + o.responseText;
div.innerHTML += "Argument object: " + o.argument;
}
}
var callback =
{
success:handleSuccess,
failure: handleFailure,
argument: ['foo','bar']
};
</textarea></pre></pre>
<h3>Initiate the POST Transaction</h3>
<p>
Call YAHOO.util.Connect.asyncRequest to send the request to post.php, and the PHP file will return the a readable output of $_POST via <strong>print_r()</strong>. The handleSuccess callback will print the response object's properties, including the server response data.
</p>
<pre><textarea name="code" class="JScript" cols="60" rows="1">var request = YAHOO.util.Connect.asyncRequest('POST', sUrl, callback, postData);
</textarea></pre>
<div id="container"></div>
<script>
var div = document.getElementById('container');
var handleSuccess = function(o){
if(o.responseText !== undefined){
div.innerHTML = "<li>Transaction id: " + o.tId + "</li>";
div.innerHTML += "<li>HTTP status: " + o.status + "</li>";
div.innerHTML += "<li>Status code message: " + o.statusText + "</li>";
div.innerHTML += "<li>HTTP headers received: <ul>" + o.getAllResponseHeaders + "</ul></li>";
div.innerHTML += "<li>PHP response: " + o.responseText + "</li>";
div.innerHTML += "<li>Argument object: Array ([0] => " + o.argument[0] +
" [1] => " + o.argument[1] + " )</li>";
}
};
var handleFailure = function(o){
if(o.responseText !== undefined){
div.innerHTML = "<li>Transaction id: " + o.tId + "</li>";
div.innerHTML += "<li>HTTP status: " + o.status + "</li>";
div.innerHTML += "<li>Status code message: " + o.statusText + "</li>";
}

{
