I have a date input and I wish to have the first option empty or blank. That way the user will have to select something, if not, validation will pick it up.
By default today's date preselected on load. I have managed to input a blank value but I cannot get it as the selected option.
echo $this->Form->input('date_of_birth', array('empty' => ''));
You should use boolean on empty attribute:
echo $this->Form->input('date_of_birth', array('empty' => true));

I have populated a dropdown box with data and I can select from a list.I cant seem to set the option on to the selected value.I select a value and I want the drop down box to have the last selected value display instead of resetting to the 1st option in the list. I have tried selected,default with and without numbers.
public function admin_list($tutorId=0,$paycycleId=0) {
if (isset($this->request->data['tutor'])) {
debug($this->request->data['TimeSheet']['tutor']);
$tutorId=$this->request->data['TimeSheet']['tutor'];
return $this->redirect(array('action' => 'admin_list',$tutorId,$paycycleId));
}//isset
view////
echo $this->Form->input('paycycle', array('label' => 'Pay Cycle Period',
'empty' =>array(0 => 'choose'), 'options' => $pcycle,'default'=>2 ));
echo $this->Form->submit('Select a Pay Cycle', array('name'=>'paycycle'));
echo $this->Form->end();
Per the detailed instructions in the CakePHP Book:
Set ‘selected’ to the value of the item you wish to be selected by default when the input is rendered
I am trying to pass the values of form inputs to a controller for validation. The values are populated in the view using an array. The problem is that I don't know how to get the necessary 'name' values from the array for the individual inputs in order to pass them through validation.
In the first view the form inputs are described this way:
<?php echo form_checkbox('study_items[]', 'Medical History', FALSE);
echo form_label('Medical History', 'Medical History');?>
<br>
<?php echo form_checkbox('study_items[]', 'Physical Exam', FALSE);
echo form_label('Physical Exam', 'Physical Exam');?>
<br>
<?php echo form_checkbox('study_items[]', 'Clinical Assessment', FALSE);
echo form_label('Clinical Assessment', 'Clinical Assessment');?>
The user only has to check the item(s) that apply to their specific need. This is submitted to the validation controller which, after successful validation, ONLY sends those items that were selected back to a view in an array like so:
$data['si_items'] = $this->input->post('study_items');
In the next view, the code for a sample input looks like this:
<?php foreach ($si_items as $si_item) {
echo $si_item. ' '. "$";
$data001 = array(
'name' => $si_item,
'id' => $si_item,
'value' => '',
'maxlength' => '10',
'size' => '50',
'style' => 'width:100px',
);
echo form_input($data001);
echo '<br>';
}
?>
and allows the user to enter a dollar amount for the items they selected to fit their need on the previous page.
As sample output of this portion of the code looks like this:
"Medical History $_______________"
"Physical Exam $_______________"
"Clinical Assessment $_______________"
where the blank is a textbox for entering the price of each item. So far, this all works perfectly to display each form input box and labels checked by the user in the previous view.
However, I'm at a loss as to how to get the 'name' for each individual input in order to validate it. The validation controller does not recognize '$si_items' as a name value. This has me stumped and there HAS to be a way to do this.
In my validation controller I want to check that each entry has a decimal value (i.e. 234.56) as the user's input.
Any ideas? Is there a more efficient way to do this?
we are missing swaths of code, but from what you have shown;\
$data['si_items'] = $this->input->post('study_items');
is the assignment of your study items (which is an array), meaning that the call in your foreach should not be
foreach ($si_items as $si_item) {
but rather
foreach ($data['si_items'] as $si_item) {
that or change your initial assignment to the following;
$si_items = $this->input->post('study_items');
When i select value from drop down list,
and I submit form, i want my drop down list to have selected value,
not to be on default value again.
I try like this, but not working:
<?php echo $form->dropDownList($model, 'code', $countriesIssuedList, array('name'=>'countriesIssued'), $select = array($_POST['countriesIssued']));?>
Also i would like to add a first value to be default, not from db, i want to do it in the code like this, array('empty'=>'--Select country--')
but not working.
Thanks
If you must change the name of your dropdownList you must manually set the value of code to $_POST['countriesIssued'] in your controller/view. As for the default, prompt is used to set this.
<?php if(!$model->code) $model->code=$_POST['countriesIssued'];?>
<?php echo $form->dropDownList($model, 'code', $countriesIssuedList, array(
'name'=>'countriesIssued','prompt'=>'--Select country--'
));?>
The second parameter (currently 'code') must be a key in this array: $countriesIssuedList
See for example here.
"Also i would like to add a first value to be default" ... perhaps you can use array_merge()?
I am generating options for my dropdown using
// view.php
foreach ($plants as $row):
$options[$row->plant_id] = $row->plant_name;
endforeach;
and then lower in the HTML part of view.php
//view.php
$js = 'onChange = "plantDateDelete(\'/size/get_dates_for_plant/\'+this.value);"';
echo form_dropdown('plant_id', $options, 'Select', $js);
The dropdown show options OK, but it does NOT show 'Select' as the "selected"/default value. It shows up with the first option of the array instead.
The HTML source also shows 'Select' in form_dropdown was ignored.
I really need this dropdown to show up with 'Select' as default so as to force the user to activate the onChange function.
Any idea what is going on here or how to solve this issue?
You need to have the default option in your $options array...
So before your foreach, do:
$options = array('Select');
I should add, this will have the value of 0 in the dropdown, but as its the first element in the array it will be selected by default, unless another option is passed as the default value.
If you wanted to explicitly set this value as the default you would pass 0 as the default argument.
i plan to set a checkbox with selected option in my form.
but i am unable to show my checkbox content in the form, i cant see any value instead of just a box for me to select.
how to show value while i using checkbox? i able to show my value while i using select.
this is in a HABTM model. any hints?
here is my selection code.
input('User',array('label'
=> 'Select Related Potential',
'multiple'=>'checkbox',
//'options' => $users,
'legend'=>$users,
//'value'=>$users,
//'id'=>$ownUserId,
'default'=>$ownUserId,
'style'=>'width:200px;height:100px',
'selected' => $ownUserId, )); ?>
This may be relevant:
You cannot use default to check a checkbox - instead you might set the value in $this->data in your controller, $form->data in your view, or set the input option checked to true.
For example:
// in Controller
$this->data['Model']['field'] = true;
Causes the field to have the value true, which will result in a checked checkbox for this field.
Or:
$form->input('Model.field', array('checked' => true));
Always checks the checkbox.
Or:
$form->input('Model.field', array(
'checked' => ($this->data['Model']['field'] == 'xxx')
));
Dynamically sets the checkbox based on whether $this->data['Model']['field'] is 'xxx' or not.
Sorry, completely misunderstood the question.
Did you find your users via list? The options array needs to be in a particular format, a normal find() won't do that.
