Fetching Functions

$t→fetch()

Given a URL and post data, the fetch function makes a HTTP request and sets $t->result to be the resulting source code.

By convention we work with a string, $t, applying mADL functions to it. In the fetch function we load the string $t with the page source or structured data (XML or such like) that is to be interpreted.

The fetch may be a request for a web page from which the required information will be “parsed” into variables for display or further use, or may be a call to a web API

which returns structured data (eg. XML) without any formatting information. Regardless of the format of the return data, the correct fetch must be constructed.

Parameters	An array of options including the following.
$url	A String containing the requested URL.
$post	An Array or String containing post data or array.
$headers	An Array or String containing page header type.
$referer	An Array or String containing url or page to re-direct to.
$header_in_output=false	A boolean value that defines if the header is included in the output.
$timeout_second=30	a numeric value for CURLOPT_CONNECTTIMEOUT.
$curlOpts = array()	key-value pair for curl options

Return Values

$t->result

A String.

All results from $t->fetch are stored in $t->result.Used for performing HTTP connections. Fetch is a wrapper for the PHP cURL function.

$t->Fetch() Simple Example

$t->fetch("[http://blinkmobile.com.au/");] \\

$t->Fetch() With Get Example

$t->fetch("[http://blinkmobile.squarespace.com/display/Search?searchQuery="] . $args[0] . "&moduleId=6598880");

|U",   ""  );  if($t->isblank()){   return "Your search returned no results"; }  return $t->result;

echo $theProgram;

$listjo=$t->listJourneyObjects();

$t->row("|{INFO}|U","$theProgram");

$t->rows("|{URLS}|U","{URLS}@@@ZZZ");

$abstracts=explode("@@@ZZZ",$t->result);

$html .= "";

foreach($abstracts as $abstract) {

echo $abstract;

$t->fetch("[http://ccaeducause1.caudit.edu.au/index.php/educause/ccae2011/paper/viewPaper/"] . $abstract); 
$t->after("<body>"); echo "<br>";

$html .= "" . $t->result;   $t->fetch("[http://ccaeducause1.caudit.edu.au/index.php/educause/ccae2011/rt/bio/"] . $abstract . "/0");  $t->after("<body>");  echo "<br>";  $t->row("|id=\"authorBio\">{authorBio}{authors}|U","");  $html .=  $t->result . "";  echo $t->result;  };   $html = "" . $html . "";  $t->result=$html;  $t->preg_replace("|

$t->refresh( )

This function resets $t->result to be the value of the previous fetch request.

if($t->contains("Logged Successful")){
// do something

$t->refresh( );
