Laravel data not going appropriately into the database

What i need is if i get first element id of MOB/TR/1743 then press the mark button data which relevant to that id must go the database.

this is what should in the database.

But this is what i'm getting into the database.that means getting another column data into database.

here is the view of that.

    <div class="row">
<section id="feature" class="section-padding wow fadeIn delay-05s">
      <div class="container">
        <div class="row">
          <div class="col-md-12 col-sm-6 col-xs-12">
            <div class="wrap-item text-center">

              <div class="jumbotron">
                  <div class="item-img">
                     <img src="images/ser02.png">
                  </div>

                    <div class="form-group">

                          <form action="search" method="post" class="form-inline">    
                              <select name="institute" id="institute">
                                <option selected="selected" value="id">Trainee Id</option>
                                <option value="full_name">Trainee Name</option>
                                <label for="Search">Name</label>
