I have the following in my HTML form, among with other inputs, like <input type="test" name="foo"></input> and others.
<select name="tags" multiple="multiple">
<option selected="selected" value="hello">hello</option>
<option selected="selected" value="world">word</option>
</select>
The problem is that when I am using
var_dump($_POST);
the tags returned is a string, and it contains only the last item in the select, like this:
string(5) "world"
Any help?
Your HTML should indicate that it's submitting an array :
<select name="tags[]" multiple="multiple">
(note the [])
Try using below code. Name should be name="tags[]". If you name is like name="tags" it will only pass one value, if you want to pass multiple values you should name it as an array.
<select name="tags[]" multiple="multiple">
<option selected="selected" value="hello">hello</option>
<option selected="selected" value="world">word</option>
</select>
Your code should look like:
<select name="tags[]" multiple="multiple">
<option selected="selected" value="hello">hello</option>
<option value="world">word</option>
</select>
And please don't use selected="selected" for every option. Selected="selected" should be used only for one option, the option to be shown default! This is very important!
use name="tags[]" that way an array is passed
then you can use
if(isset($_POST['tags'])){
foreach($_POST['tags'] AS $value){
echo $value;
}
}
In this case be sure to set method="post" in your form tag.
You can use selected="selected" without a problem

My Multiselect input code is
<?php echo $this->Form->input('Dispensary.role.',array('options'=>$dispensary_users,'class'=>'form-control dispensary_users_dd','label'=>false,'style'=>'width:300px;','empty'=>'Select Users'));
?>
and generated html code :
<select name="data[Dispensary][role][]" class="form-control dispensary_users_dd" style="width: 300px; display: none;" id="DispensaryRole">
<option value="">Select Users</option>
<option value="9">Yashobanta</option>
<option value="80">Yash</option>
<option value="83">Ramesh</option>
</select>
But when I select all users, and print_r($this->data);
returns last selected input.
But I want all.
I forgot to add multiple => true.
I don't know how that thing with $this->Form->input(...); works, because it's not important. You can select only one opinion without multiple attribute.
Example by w3schools.org:
<select name="cars" multiple>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="opel">Opel</option>
<option value="audi">Audi</option>
</select>
For saving the multiple select value in database, store the array using implode function.
In controller:
if (!empty($this->data)) {
$this->data['Category']['name'] = implode(",",$this->data['Category']['name']);
$this->Category->create();
$this->Category->save($this->data);
}
Hope it's help :)
I have a question. Let me explain this with an example.
I have this piece of code:
<form action="vehicles.php" method="get">
<span>Marca:
<select name="brand">
<option value="null" selected="selected"></option>
<option value="Volkswagen">Volkswagen</option>
<option value="Renault">Renault</option>
<option value="Peugeot">Peugeot</option>
<option value="Fiat">Fiat</option>
</select>
</span>
<span>Modelo:
<select name="model">
<option value="null" selected="selected"></option>
<option value="206">206</option>
<option value="Suran">Suran</option>
<option value="Passat">Passat</option>
<option value="Punto">Punto</option>
</select>
</span>
<input type="submit">
</form>
Is any way to prevent the assignment of those variables if the option selected is the "null" one?
If, for example, I select brand="Renault" and model="null" the url is
http://mywebpage.com/vehicles.php?brand=Renault&model=null
but it should be
http://mywebpage.com/vehicles.php?brand=Renault
I know how to unset the variables with "null" value after the form submission with PHP. Is any way to do it before the submission and after the variables are setted to "null".
I would like a cleaner url, free of "variable=null" results.
P/D: I don't have a native english speaking so feel free to edit my question. I wish you understand me.
I am afraid that you might need javascript to achieve what you want.
Take a look at this code:
<form action="vehicles.php" id="carForm" method="GET">
<span>Marca:
<select name="brand" id="brand">
<option value="none" selected>-</option>
<option value="Volkswagen">Volkswagen</option>
<option value="Renault">Renault</option>
<option value="Peugeot">Peugeot</option>
<option value="Fiat">Fiat</option>
</select>
</span>
<span>Modelo:
<select name="model" id="model">
<option value="none" selected="selected">-</option>
<option value="206">206</option>
<option value="Suran">Suran</option>
<option value="Passat">Passat</option>
<option value="Punto">Punto</option>
</select>
</span>
<input type="button" value="Submit" onclick="submitFormFilter();" />
</form>
Javascript : code will be like this:
<script>
function submitFormFilter(){
var myForm = document.getElementById("carForm");
var carBrand = document.getElementById("brand");
var carModel = document.getElementById("model");
if(carBrand.value === "none" || null){
carBrand.parentNode.removeChild(carBrand);
}
if(carModel.value === "none" || null){
carModel.parentNode.removeChild(carModel);
}
myForm.submit();
}
</script>

you can it try here.
Include the value attribute of your option tags.
<option value="" selected="selected">-</option>
You should really do this for all of your options.
if you don't want to use $_GET superglobal because of the url extension that it comes with try using $_POST instead. It will not have a url extension and it can still store values that you can later retrieve. Just be sure to change your method to equal POST instead of GET.
So the code for the form tag would change to:
<form action="vehicles.php" method="POST">
And you can later access it by (for example):
echo $_POST['brand'];
or
echo $_POST['model'];
as well, you probably want to add a value param to the values that you have in your option tag.
EDIT-
I've added this new section since you don't want to use POST even though I think you should.
You can stay with the GET method by doing this line of code:
<form action="vehicles.php" method="GET">
<span>Marca:
<select name="brand">
<option value="none" selected>-</option>
<option value="Volkswagen">Volkswagen</option>
<option value="Renault">Renault</option>
<option value="Peugeot">Peugeot</option>
<option value="Fiat">Fiat</option>
</select>
</span>
<span>Modelo:
<select name="model">
<option value="none" selected>-</option>
<option value="206">206</option>
<option value="Suran">Suran</option>
<option value="Passat">Passat</option>
<option value="Punto">Punto</option>
</select>
</span>
<input type="submit">
</form>
Let me know if that helps
You should set the value for the option tag of <select> :)
You's missing set value for option tag. you should set the value for option tag in select tag. With the blank value, you can assign it to a special value like zero(0)
<select name="model">
<option value="0" selected>-</option>
<option value="1">206</option>
<option value="2">Suran</option>
<option value="3">Passat</option>
<option value="4">Punto</option>
</select>
EDIT:
Ok. I got your point. You can import jquery to your page and make a check by javascript before you submit, if the value of select box is blank. you can remove it.
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script type="text/javascript">
$.ready(function(){
$("form").submit(function(){
if($("select[name='model']").val() == "0") $("select[name='model']").remove();
return true;
});
})
</script>
How can I add html value for select menu options:
<select name="symbol">
<option>select</option>
<option value="<img src="start.jpg"">start</option>
<option value="<img src="end.jpg"">end</option>
</select>
I want post value to show an image.
I read this : How to add a images in select list
but I want send image value.
If you're handling the post with PHP or some similar server-side code, you should pass through only the reference to the image. Any tags can be output using the server-side code. For example:
<select name="symbol">
<option>select</option>
<option value="start.jpg">start</option>
<option value="end.jpg">end</option>
</select>
And then handle this by doing something like:
echo '<img src="'.$_POST['symbol'].'" />';
Use single quotes instead of double qoutes inside value...
<select name="symbol">
<option>select</option>
<option value="<img src='b.jpg'>">start</option>
<option value="<img src='a.jpg'>">end</option>
</select>
You have to use single quote and close tag. Try this,
<select name="symbol">
<option>select</option>
<option value="<img src='start.jpg'>">start</option>
<option value="<img src='end.jpg'>">end</option>
</select>
A select list in a form, I know there's no problem to pass the option value using post or get. But if I also want to pass the select id value, is it possible and how?
For example:
<form action="Test.php" method="POST">
<select name="select" id = '1'>
<option value="">Select a Status</option>
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input type="submit" value="submit"/>
</form>
And here is the simple print php code:
<?php
print_r($_POST['select']);
?>
It can print the value of the option that has been chosen, but how to modify the code if I also want to post the id value, which is 1 here. I want to do so because I want the id to become a variable to store some int numbers. Thank you!
The id attribute is designed purely for use in client side code. If you want to pass extra data, then use hidden inputs — that is what they are designed for.
<input type="hidden" name="select_extra" value="1">
<select name="select">
<option value="">Select a Status</option>
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
ID's won't get passed automatically in HTTP.
You need either:
Use an input hidden
Use a special name. I.E. <select name="select_1" id="1">...</select
In my profile advanced search i have an mutiple select type..
<form method="POST">
<select size="6" name="Cities" multiple="multiple" id="Cities">
<option value="0">All</option>
<option value="1">City1</option>
<option value="2">city2</option>
<option value="3">city3</option>
<option value="4">city4</option>
<option value="5">city5</option>
</select>
</form>
How do I use it, I mean how should i call what they have chosed...As you can choose one or more options (by holding in control, or just holding in mouseclick and point to other options).
Give it the name Cities[] instead of Cities, and you'll have an array in $_POST['Cities'] on submit.
