Send form with hidden fields

Question

Guys, next, I have a form with two hidden selects, they will be displayed only when I select one of the options in the parent select, but every time I submit this one it takes the value of a hidden select. Is there any way to do with it just take the value if I select the option in select parent ?

This is my form:

<form id="createusers" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" class="needs-validation" oninput='userrepassword.setCustomValidity(userrepassword.value != userpassword.value ? "Senhas não conferem." : "")' novalidate>
      <div class="form-group">
        <div class="input-group">
          <div class="input-group-prepend">
            <div class="input-group-text"><i class="fas fa-user-circle"></i></div>
          </div>
          <input id="username" name="username" placeholder="Usuário" type="text" aria-describedby="usernameHelpBlock" required="required" class="form-control">
          <div class="invalid-feedback">Por favor, digite um nome de usuário válido.</div>
        </div>
        <small id="usernameHelpBlock" class="form-text text-muted">Digite um nome de usuário.</small>
      </div>
      <div class="form-group">
        <div class="input-group">
          <div class="input-group-prepend">
            <div class="input-group-text"><i class="fa fa-lock"></i></div>
          </div>
          <input id="userpassword" name="userpassword" placeholder="Senha" type="password" required="required" class="form-control" aria-describedby="userpasswordHelpBlock">
          <div class="invalid-feedback">Por favor, digite uma senha.</div>
        </div>
        <small id="userpasswordHelpBlock" class="form-text text-muted">Digite uma senha para o usuário. Sua senha deve ter no mínimo 6 caracteres.</small>
      </div>
      <div class="form-group">
        <div class="input-group">
          <div class="input-group-prepend">
            <div class="input-group-text"><i class="fa fa-lock"></i></div>
          </div>
          <input id="userrepassword" name="userrepassword" placeholder="Confirme a senha" type="password" required="required" class="form-control" aria-describedby="userrepasswordHelpBlock">
          <div class="invalid-feedback">Por favor, confirme a senha.</div>
        </div>
        <small id="userrepasswordHelpBlock" class="form-text text-muted">Confirme a senha.</small>
      </div>
      <div class="form-group">
        <label>Informe o grupo do usuário</label>
        <select id="usergroup" name="usergroup" class="form-control" required>
          <option value="">-- Selecione uma opção --</option>
          <option value="neg">Negado</option>
          <option value="tot">Total</option>
          <option value="controlado">Controlado</option>
          <option value="restrito">Restrito</option>
          <option value="lib">Liberado</option>
          <option value="noc">No Cache</option>
        </select>
        <div class="invalid-feedback">Por favor, selecione uma opção para informar o grupo do usuário.</div>
        <small id="usergroupHelpBlock" class="form-text text-muted">Selecione um grupo para o usuário.</small>
      </div>
      <div class="form-group">
        <label>Selecione o grupo controlado para o usuário</label>
        <select id="usergroup-controlado" name="usergroup" class="form-control">
          <option value="c01">Controlado 01</option>
          <option value="c02">Controlado 02</option>
          <option value="c03">Controlado 03</option>
        </select>
      </div>
      <div class="form-group">
        <label>Selecione o grupo restrito para o usuário</label>
        <select id="usergroup-restrito" name="usergroup" class="form-control">
          <option value="r01">Restrito 01</option>
          <option value="r02">Restrito 02</option>
          <option value="r03">Restrito 03</option>
          <option value="r04">Restrito 04</option>
          <option value="r05">Restrito 05</option>
          <option value="r06">Restrito 06</option>
          <option value="r07">Restrito 07</option>
          <option value="r08">Restrito 08</option>
          <option value="r09">Restrito 09</option>
        </select>
      </div>
      <div class="form-group">
        <div>
          <div class="custom-control custom-checkbox">
            <input id="userconfirm_0" name="userconfirm" type="checkbox" required="required" class="custom-control-input" value="userconfirm"> 
            <label for="userconfirm_0" class="custom-control-label">Confirme para criar o usuário</label>
            <div class="invalid-feedback">Por favor, confirme para criar o usuário.</div>
          </div>
        </div>
      </div> 
      <div class="form-group">
        <button id="submitcreateuser" name="submitcreateuser" type="submit" class="btn btn-primary">Criar Usuário</button>
      </div>
    </form>

And to hide these selects use the following scripts:

<script type="text/javascript">
(function( $ ){
  $.fn.dependsOn = function(element, value,callback) {
    var elements = this;
    var isContainer = false;
    //add change handler to element
    $(element).change(function(){
      var $this = $(this);
      var showEm = false;
      if ( $this.is('select') ) {
        var fieldValue = $this.find('option:selected').val();
        if ( !value ) {
          showEm = fieldValue && $.trim(fieldValue) != '';
        } else if (typeof(value) === 'string') {
          showEm = value == fieldValue;
        } else if ($.isArray(value)) {
          showEm = ($.inArray(fieldValue, value) !== -1);
        }
      } else if ($this.is('input[type="text"]')){
        var fieldValue = $this.val();
        if ( !value ) {
          showEm = fieldValue && $.trim(fieldValue) != '';
        } else if (typeof(value) === 'string') {
          showEm = value == fieldValue;
        } else if ($.isArray(value)) {
          showEm = ($.inArray(fieldValue, value) !== -1);
        }
      }
      // add containers for input
      else if ($this.hasClass('depends-container')){ 
        isContainer=true;
        var target = $this.find('input[type="text"]');
        var fieldValue = target.val();
        if ( !value ) {
          showEm = fieldValue && $.trim(fieldValue) != '';
        } else if (typeof(value) === 'string') {
          showEm = value == fieldValue;
        } else if ($.isArray(value)) {
          showEm = ($.inArray(fieldValue, value) !== -1);
        }
      }

      if(isContainer){

        elements.each(function(){
          $(this).toggle(showEm);
          if(callback){
            callback();
          }
        });

      }else{
        elements.closest('div').toggle(showEm);
        if(callback){
          callback();
        }
      }

    });

    //hide the dependent fields
    return elements.each(function(){

      var $this= $(this);
      var isContainer= false;
      $(element).each(function(index){
        var el = $(this); 
        if(el.hasClass('depends-container') && el.find('input[type="text"]').length){
          isContainer = true;
          el = el.find('input[type="text"]');
          if(el.val() != '' && $this.is('visible') == false ){
            $this.show();
            if(callback){
              callback();
            }
          }
        }
      });

      if(!isContainer){
        $(this).closest('div').hide();
      }

    });
  };
})( jQuery );
</script>
<script type="text/javascript">
$('#usergroup-controlado').dependsOn('#usergroup', ['controlado']);
$('#usergroup-restrito').dependsOn('#usergroup', ['restrito']);
</script>

And this is the script that sends the form, where I get the filled out information:

<?php
        if(isset( $_POST['submitcreateuser'] )) {
            $fullname = $_POST["fullname"];
            $username = $_POST["username"];
            $userpassword = $_POST["userpassword"];
            $userrepassword = $_POST["userrepassword"];
            $networkaccess = $_POST["networkaccess"];
            $usergroup = $_POST["usergroup"];
            $createuser = "$username $fullname $networkaccess $usergroup $userpassword $userrepassword s -a; echo $?";

            echo "<pre> >> $createuser << </pre>";

        }
    ?>

The hidden selects are those of the Controlled and Restricted group, when selecting these options it opens another select with the respective options, Controlled type it will display the select Controlled 01, Controlled 02, Controlled 03. And so it also serves for the Restricted option.

There’s something wrong with my form ?

Answer 1

In all select you use the same name="usergroup" will override the upload. I would advise you to handle inside php as the friend above spoke, in the select displayed when selected controlled in the parent you put the name="usergroupcontrol" and in restricted puts name="usergrouprestricted", ai with the parent name in the $usergroup variable you know which value of the selects to take.
