Question

I’m trying to validate my inputs with jQuery before a form is sent.

This is what my input fields look like when there is no value inserted in the database:

    <input
      class="field"
      type="text"
      style="background-color: rgb(255, 255, 255);"
      value="" name="input_18748_388_1257894000_"/>

This is what my input fields look like when there is an existing value inserted in the database:

    <input
      class="field"
      type="text"
      style="background-color: rgb(255, 255, 255);"
      value=""
      name="input_18748_388_1257894000_46549876"/>

I would like to:

• Check if the value is already in the database

• Check if the user want to replace an
  existing value by nothing or zero and
  disallow it.

• Check if the user is trying to
  insert 0 in a new field and
  disallow it.

Solved:

  $("input[name^='input_"+var+"_']")
                .each(function() {
                    if ($(this).attr('name').match(/^input_\d+_\d+_\d+_\d+/)
                        && ($(this).val() == '' || $(this).val() <= 0))
                    {
                        displayDialog("<?=_('error')?>")
                        flag_error = 1;
                        return false;
                    }
            });
    // Submit the form.

 $("input[name^='input_"+var+"_']")
                .each(function() {
                    if ($(this).attr('name').match(/^input_\d+_\d+_\d+_\d+/)
                        && ($(this).val() == '' || $(this).val() <= 0))
                    {
                        displayDialog("<?=_('error')?>")
                        flag_error = 1;
                        return false;
                    }
                });
