    <p>Im using the <a href="http://ci-merchant.org/" rel="nofollow">ci-merchant</a> library in my PyroCMS module locally on my development WAMP server. (all working fine)</p> <p>When I upload to my Linux test server the <code>purchase()</code> function being called does not seem to work.</p> <p>When it executes it pools for 5 minutes then I get a response "<em>Could not connect to host</em>".</p> <p><strong>PHP</strong></p> <pre><code>$params = array( 'amount' =&gt; 20, 'currency' =&gt; 'USD', 'return_url' =&gt; 'http://someurl.com/return/' 'cancel_url' =&gt; 'http://someurl.com/cancel/' ); $settings = array( 'test_mode' =&gt; TRUE, 'username' =&gt; 'PAYPAL_TEST_USERNAME' 'password' =&gt; 'MY_PAPAL_TEST_PASS' 'signature' =&gt; 'MY_PAYPAL_TEST_SIG' ); $this-&gt;load-&gt;library('merchant'); $this-&gt;merchant-&gt;load('paypal_express'); $this-&gt;merchant-&gt;initialize($settings); //this is where Im having the issue $response = $this-&gt;merchant-&gt;purchase($params); $message = $response-&gt;message(); </code></pre> <p>When I echo $message</p> <pre><code>echo $message; //Outputs: couldn't connect to host" </code></pre> <p><em><strong>CURL - Server Settings</em></strong></p> <p>Below is a list of the differences in the CURL settings on the servers. Perhaps this is the issue. I dont think these settings can be changed without having to compile curl but im not sure. </p> <p><strong>Development Server</strong> (WAMP server - status:Working)</p> <pre><code>AsynchDNS : Yes CurlInfo : 7.21.7 GSS Neg : Yes IDN : No SSPI : Yes libSSH : libssh2/1.2.7 </code></pre> <p><strong>Test Server</strong> (Linuxserver - status:Not working)</p> <pre><code>AsynchDNS : No CurlInfo : 7.24.0 GSS Neg : No IDN : Yes SSPI : No libSSH : &lt;&lt;not listed&gt;&gt; </code></pre>

    1. COProbably a firewall on your test server is preventing outgoing connections.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
