Group Contact

Today, i am going to write first post for mySql. mySql has many functions to make programmer’s life easy.

When i was doing my project, i have to display some data by grouping with one field.

Example :

Suppose you have Student table with skill.

srno student skill
1 Jaydip PHP
2 Sanjay PHP
3 Jaydip Android
4 Pratik PHP
5 Sanjay CI
6 Pratik Magento


Now you want to display like student with all skills in one row.

srno student allskill
1 Jaydip PHP,Android
2 Sanjay PHP,CI
3 Pratik PHP,Magento


To get result like this, GROUP_CONTACT is there in mySql.


SELECT srno,student,GROUP_CONTACT(skill) AS allskill FROM student_skill GROUP BY user;


Search with one more value

Today, I will show you how to display different value on list and how to search from another value.

When i was doing my project, i have to display list item with different search value. So i have customized bootstrap for this.

To do this use attribute “renderField”.

Example :


     renderField: "display_text",


you have to add this renderField into data object.

Data object example :

item = {}

item.display_text = "searchvalue1 searchvalue2";

item.value= "displayvalue";

When you type searchvalue1  or searchvalue2 or displayvalue. This item will show in all three search. and it will display displayvalue only.

How to find duration between two time

Hello Geeks,

Today we will learn how to get duration between given two time. Some time we want to get duration of selected time period. So, how to it with help of javascript.

Here I will explain you how to do it with javascript.

We will take example of two time. Suppose we want to get sleeping duration of any person. Suppose person is sleeping at 10:00 PM and wake up at 05:00 AM. So sleeping hours is 7 and minute is 0.

Now we will do it with code.

<script type="text/javascript">
    function returnNumber(v) { 
       v = parseInt(v);
       if (isNaN(v)) {
           return 0;
       } else {
           return v; 

    valuestart = "10:45 PM";
    valuestop = "07:30 AM";
    amPM1Arr = valuestart.split(" ");
    amPM2Arr = valuestop.split(" ");
    amPM1 = amPM1Arr[1];
    amPM2 = amPM2Arr[1];
    timiningArr2 = amPM2Arr[0].split(":");
    timiningArr1 = amPM1Arr[0].split(":");
    if (amPM1 == amPM2) {
        timiningArr2 = amPM2Arr[0].split(":");
        timiningArr1 = amPM1Arr[0].split(":");
        totalHour = returnNumber(timiningArr2[0]) - returnNumber(timiningArr1[0]);
        totalMin = returnNumber(timiningArr2[1]) - returnNumber(timiningArr1[1]);
        if (totalHour < 0 ) {
            totalHour = totalMin= 0;
        } else {
            if(totalMin < 0) { 
                totalMin = 60 +totalMin; 
    } else { 
        totalHour = 0; 
        totalMin = 0; 
        if (amPM1 == "PM" && amPM2 == "AM") { 
            totalHour += returnNumber(timiningArr2[0]); 
            timiningArr1[0] = returnNumber(timiningArr1[0]); 
            totalHour += (11 - timiningArr1[0]); 
            totalMin = 60 - returnNumber(timiningArr1[1]); 
            totalMin += returnNumber(timiningArr2[1]); 
        } else if (amPM2 == "PM") { 
            totalHour = returnNumber(timiningArr2[0]); 
            totalHour += (11 - timiningArr1[0]); 
            totalMin = 60 - returnNumber(timiningArr1[1]); 
            totalMin += returnNumber(timiningArr2[1]); 
        if (totalMin > 60 ) {
            extraH = totalMin%60;
            totalHour = totalHour + extraH;
            totalMin = totalMin - (extraH*60);
        } else if (totalMin == 60) {
