How to Load Data in Modal with Next & Previous button by Ajax PHP



If you are looking for tutorial on Bootstrap Modal with Dynamic data, then you in this post you can find not only how to load dynamic data into pop up bootstrap modal but also you can also find previous and next records button also by using Ajax Jquery with PHP. In one of the our previous post we have already made discussion on How to load dynamic data into Bootstrap modal by using Ajax PHP. But in this post we have include feature of previous and next button also.

If you have already load data into Bootstrap modal, so at that time you have seen one id records then after if you want to see next records then you have to close modal and click on next records view button. But now we have make simple tutorial in which you can see all records details on single modal by clicking on previous and next button. So on single modal we can see all records details one by one on single click and we do have to go next modal.

So if you have developed any web based application and in that application you have used Bootstrap modal for display dynamic data then you can add this features also. So user can view all records details one by one on single modal by clicking on Previous records button or Next records button. Here if you have load first records button then at that time previous button will be disabled because if you have load first records then there is no previous records so previous button will be disabled at that time and same way if you have view last records then at that time next button will be disabled. So if you have developed any web based application by using PHP Ajax with Bootstrap and if you have load dynamics data into modal then you can add this type of feature also to view previous and next records details on same modal by click on button.

I hope you have learn something new from this post. Please keep visit our website. Here you can also find source code and online demo. So keep enjoying PHP programming.
