json data module | Help [SOLVED]
Development and Programming
Hello all,
I have created an extension that allows you to select a weblog and category in a custom field. Now when a weblog is selected a json calls happens to the module this module should then return json data.
The url that i use to call my json is : http://localhost/ExpressionEngine1.6.0/system/index.php?S=43f0f0e01c033490c776695527aced2a65edd702&C=modules&M=Select_blog&P=ajax_categories_search The problem is that this also displays the menu and header etc… all the things i dont need.
I tryed clearing $DSP=”” which works but gives me an error: Fatal error: Call to a member function show_full_control_panel() on a non-object in /Users/kevin/webroot/ExpressionEngine1.6.0/system/core/core.system.php on line 883
So my question is how to handle is there a function to prevent any output?
Here you can see my code if that helps clearifying things. Thanks for any help!
<?php
class Select_blog_CP {
var $version = '1.0';
// -------------------------
// Constructor
// -------------------------
function Select_blog_CP($switch = TRUE)
{
global $IN, $DB;
// Is Module installed?
if ($IN->GBL('M') == 'INST')
{
return;
}
// Check installed version
$query = $DB->query("SELECT module_version FROM exp_modules WHERE module_name = 'Select_blog'");
if ($query->num_rows == 0)
{
return;
}
// update version number
if ($query->row['module_version'] < $this->version)
{
$DB->query("UPDATE exp_modules SET module_version = '{$this->version}' WHERE module_name = 'Select_blog'");
}
// end update
if ($switch)
{
switch($IN->GBL('P'))
{
case 'ajax_categories_search' : $this->ajax_categories_search();
break;
default: $this->ajax_categories_search();
break;
}
}
}
// END
// ----------------------------------------
// Ajax Entry Search
// ----------------------------------------
function ajax_categories_search()
{
global $DSP;
//$DSP ="";
echo '{"previews":[

]}';
$DSP = "";
/**
global $DB, $DSP, $REGX, $IN, $PREFS, $LANG, $LOC, $SESS;
$weblog_name = ($IN->GBL('weblog', 'POST') !== FALSE) ? $REGX->keyword_clean($IN->GBL('weblog', 'POST')) : '';
if ($PREFS->ini('auto_convert_high_ascii') == 'y') {
$keywords = $REGX->ascii_to_entities($keywords);
}
$sql =" select cat_group from exp_weblogs where blog_name='".$weblog_name."'";
$res = $DB->query($sql);
foreach ($res->result as $r){
}
return '{"previews": [{"name":"test"}]}';
//if ($keywords == '') exit('<div class="highlight">'.$LANG->line('msg_no_results').'</div>');
*/
}
// END
}Oke nvm my post from above i found a workarround thanks to cocoaholic (again :p).
We are now using the mod page instead of the mcp page. The problem with the mcp page is that it always sends a header along that i cannot seem to be able to remove. So now i just call the json result page as followed: “http://localhost/ExpressionEngine1.6.0/index.php?ACT=23” Where 23 is the id of the action in the exp_actions table.
Grtz,
