:
echo '<div class="form-group has-error">
<label class="control-label" for="inputError">School ID:</label>
<input type="text" class="form-control" name="inputSchoolID" id="inputError" value="' . set_value('inputSchoolID') . ';">
<span class="help-block">'. form_error('inputSchoolID') .'</span>
</div>';
