将自动生成的表单字段值插入数据库

Question

您好我想将生成的字段表单值插入到我的mysql数据库中。它将客户数量放入下拉框并根据下拉值生成一组字段。如果下拉值为2，则将重复表单字段，并且所有填充的数据应该转到数据库。任何人都可以帮助我将这些插入到数据库中。

建立数据库连接并正常工作。

main.php javascript部分

//when the webpage has loaded do this
$(document).ready(function() {
  //if the value within the dropdown box has changed then run this code            
  $('#num_cat').change(function() {
    //get the number of fields required from the dropdown box
    var num = $('#num_cat').val();

    var i = 0; //integer variable for 'for' loop
    var html = ''; //string variable for html code for fields 
    //loop through to add the number of fields specified
    for (i = 1; i <= num; i++) {
      //concatinate number of fields to a variable
      html += '<h3 style="weight:bold;color:#0080FF; text-align: center;">CUSTOMER NO ' + i + '</h3> <br/> \n';
      html += 'First Name ' + ': <input class="form-control"  type="text" id="first_name" name="AgclifName' + i + '" />';
      html += 'Last Name ' + ': <input class="form-control"  type="text" id="first_name" name="AgclilName' + i + '" /><br/> \n';
      html += 'NIC / Passport Number ' + ': <input class="form-control" type="text" name="Agclinicpassport' + i + '"/><br/>';
      html += 'Nationality ' + ': <input class="form-control" type="text" name="AgcliNationality' + i + '"/><br/>';
      html += 'Age ' + ': <input class="form-control" type="text" name="Agcliage' + i + '"/><br/>';
      html += 'Weight' + ': <input class="form-control" type="text" name="Agcliweight' + i + '"/><br><br/><hr class="style13">';

    }

    //insert this html code into the div with id catList
    $('#catList').html(html);
  });
});
