PHP Ajax Update MySQL Data Through Bootstrap Modal




Hello friends in this post we are going to discuss how can we update data into mysql table data with Bootstrap Modal by using php script with Ajax jquery without page refresh. In previous tutorial on Bootstrap Modal we have show how to insert data into Mysql table by using Bootstrap Modal with PHP script with Ajax jquery. The main use of Bootstrap Modal we can do any type of database operation like Insert, Update, fetch and delete or display any message without opening of new page but we can do this type things on page in the form of pop up alert box. We can called this Bootstrap Modal by click on anchor tag or any button by using jquery code or we can also show Bootstrap Modal window by defining data attribute in element. Here we have use Ajax Jquery and by jquery we have get employee id from edit button, we have create all employee separate edit button with different id and in this id we have store employee id and by using jquery code we have get employee id from button and by using ajax we have fetch that employee id data from database and then after we have display that data into Bootstrap Modal html form field and in html form we can change data and by clicking on update button we can update data into mysql database by using Ajax request method.

  2. I need help, in my database I have a column named Names and accept special characters of the Spanish language, such as ñ, ü, é, á, í, ó, ú, however when I click on edit the form does not load. It seems that #Json does not accept special characters

    1. Puedes usar en las variables PHP el = utf8 encode o decode

      Por decir: $Nombre = utf8_incode($Nombe);

      Así cuando la variable llega decodificada por el carácter especial el utf8 lo codifica.

      Échate un clavado en esas funciones para que las aproveches al máximo.

  4. This code have a small error. First, you chosen and edit a field and submit. After that, you will add a new field and submit. Not data will be inserted. It will update value to the field be edit before.
    I fixed it by set
    $('#employee_id').val(''); after line $('#employee_table').html(data); of index file

  13. If you edit an employee, then immediately try to add a new employee, it overwrites the previously edited employee with the new employees info. Other than that, I like your work. Thanks!

  34. Hi, I have a problem that editing data adds a new record instead of editing the selected one. What may be the problem?

    ReplyDelete
  35. Thanks for this helpful tutorial!

    There are some bugs...
    1. As mentioned before, Insert does not work properly because hidden input with employee_id value should be empty. To fix it I just added $('#employee_id').val("");

    $('#add').click(function(){
    $('#insert').val("Insert");
    $('#insert_form')[0].reset();
    $('#employee_id').val("");
    });

    2. There is unnecessary column in table called Image. Just remove it.
    3. Change encoding to utf8_general_ci

    I hope it helps!
