CSS / JavaScript: Twitter Bootstrap center modal vertically on mobile web view

March 14, 2016March 14, 2016 Catzie Leave a comment

I’ve been working with modal boxes using Twitter Bootstrap. And the page I’m working on needs to be viewed in mobile devices. The modal looks nice and centered when viewed on desktop, but when run in mobile web browsers, it’s aligned to the top. Someone on StackOverflow suggested the use of a helper div plus […]

JavaScript: Get current function name

March 4, 2016 Catzie Leave a comment

getCallingFunctionName() is the important function here.

function getCallingFunctionName() {
    var re = /function (.*?)\(/
    var s = getFunctionName.caller.toString();
    var m = re.exec( s )
    return m[1];
}

function myCurrentFunction(){
    var func_name = getCallingFunctionName();
    alert(func_name);  //displays "myCurrentFunction"
}

myCurrentFunction();

function getCallingFunctionName() {

var re = /function (.*?)\(/

var s = getFunctionName.caller.toString();

var m = re.exec( s )

return m[1];

}

function myCurrentFunction(){

var func_name = getCallingFunctionName();

alert(func_name); //displays "myCurrentFunction"

}

myCurrentFunction();

Android: Switch into another activity

March 3, 2016 Catzie Leave a comment

To switch into another activity, the method we use is startActivity(). This is what starts another Android activity:

        Intent i = new Intent(this, NameOfActivity.class);
        startActivity(i);

1 2	Intent i = new Intent(this, NameOfActivity.class); startActivity(i);

Replace NameOfActivity with the name of any activity you’d like to switch into.

PHP dynamic variable names tutorial

February 19, 2016February 19, 2016 Catzie Leave a comment

I think it’s very convenient for us developers, being able to name our variables dynamically. I’ll show you how to do it in PHP. 🙂 For example, we have variable $foo with “bar” as value like this:

<?php
$foo = "bar";

1 2	<?php $foo = "bar";

If we want to create a variable named based on the “value” of variable $foo, this is […]

PHP: get full URL of current page with GET params or without

February 17, 2016 Catzie Leave a comment

The following string variable’s value will get the full URL of the current page, including GET arguments/params, if present.

<?php

$full_current_url = "http://" . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
echo $full_current_url;

?>

<?php

$full_current_url = "http://" . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];

echo $full_current_url;

To get the full URL of current page but WITHOUT the GET args/params, do this instead:

<?php

$full_current_url = "http://" . strtok($_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'], "?");
echo $full_current_url;

?>

<?php

$full_current_url = "http://" . strtok($_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'], "?");

echo $full_current_url;

The strtok function will return only the part of the URL string up to the character before question […]

PHP: avoid backslash on json_encode

February 16, 2016 Catzie Leave a comment

Hey! 🙂 If you are encoding your Arrays to JSON in PHP using json_encode() and the function adds backslash before your slashes, I’m gonna show you a quick fix. This is my original code:

<?php
$arr = array();
$arr['success'] = true;
$arr['message'] = "Please enter email/phone number.";
echo json_encode($arr);
?>

<?php

$arr = array();

$arr['success'] = true;

$arr['message'] = "Please enter email/phone number.";

echo json_encode($arr);

And the result is: {“success”:true,”message”:”Please enter email\/phone number.”} See the added backslash before the slash? Ugly, right? To avoid that, […]
