so I'm having problems with forms sending data to my php script.
My html is:
<form method="get" action="form.php">
<select name="course">
<option value"COMM1">COMM1111</option>
<option value"COMM2">COMM2222</option>
<option value"COMM3">COMM3333</option>
<option value"COMM4">COMM4444</option>
</select>
</form>
What's sent to form.php when I do
$_GET['course']
is the inner text of the chosen option.
So choosing COMM1111 gives me COMM1111 instead of COMM1
In your option tag you forgot your equal sign for value
<option value = "COMM1">COMM1111</option>
You are missing the = sign in your HTML for the value of the options.
Consider the following code which produces the values you are looking for ::
HTML:
<form method="get">
<select name="course">
<option value="COMM1">COMM1111</option>
<option value="COMM2">COMM2222</option>
<option value="COMM3">COMM3333</option>
<option value="COMM4">COMM4444</option>
</select>
<input type='submit'>
</form>
PHP:
<?php
if(!empty($_GET)){
print_r($_GET);
}
?>

I have a simple simple question, And is so strange for me.
In my HTML file I have a button and a form tag in which used select tag with some options as :
<form action="" method="post" name="general"> Wireless mode
<select name="wirelessmode" id="wirelessmode">
<option value="ap">AP</option>
<option value="client">Client</option>
<option value="clientbrdige">Client Bridge(Routed)</option>
<option value="adhoc">Adhoc</option>
<option value="wdsstation">WDS Station</option>
<option value="wdsap">WDS AP</option>
</select> <br>
</form>
<form action="" method="post" name="apply">
<input type="submit" name="apply" value="Apply"/>
</form>
Include that HTML file in my Php file, create a class and a function to display the selected option of the HTML as below :
<?php
include('./view/config.html');
class SSHCommand{
public function display(){
if (isset($_POST['apply'])) // press button {
$category = $_POST['wirelessmode']; // get the select option
echo $category;
}
}
}
$sshCommand=new SSHCommand();
$sshCommand->display();
?>
When i try, it gives me nothing !
But when i try :
echo 'david';
instead of
echo $category;
It prints david after press apply button.
Where I am doing wrong?
you can get a result using single FORM, modified your HTML code as per bellow.
<form action="" method="post" name="general" id="general_form"> Wireless mode
<select name="wirelessmode" id="wirelessmode">
<option value="ap">AP</option>
<option value="client">Client</option>
<option value="clientbrdige">Client Bridge(Routed)</option>
<option value="adhoc">Adhoc</option>
<option value="wdsstation">WDS Station</option>
<option value="wdsap">WDS AP</option>
</select>
<input type="submit" name="apply" value="Apply"/>
</form>
You would have to include your config.html as html with a php extension .. config.php for the html include to work.. that would be a key thing.
You can include HTML or text in a PHP include file. Anything that can go in an standard HTML file can go in a PHP include.
Your entire website should be subsequently saved using .php extensions however, whether they include php or not, that's the downside, eg. index.php rather than index.html, so it could be time-consuming. Some servers don't require this, so test your configuration first.
Best of luck
Your select is in one form block and the submit button is in another. The default nature of the submit button will submit only the html elements in that form and not all forms of the page. So to get this to work, you need to keep one form with the required elements as
<form action="" method="post" name="general"> Wireless mode
<select name="wirelessmode" id="wirelessmode">
<option value="ap">AP</option>
<option value="client">Client</option>
<option value="clientbrdige">Client Bridge(Routed)</option>
<option value="adhoc">Adhoc</option>
<option value="wdsstation">WDS Station</option>
<option value="wdsap">WDS AP</option>
</select> <br>
<input type="submit" name="apply" value="Apply"/>
</form>
I'm trying to do something very simple in PHP, but keep getting an error message. Essentially, when someone selects "Cat", I want "Miaow" to appear.
My idea was:
<select name="demo">
<option value="Dog">Dog</option>
<option value="Cat">Cat</option>
<option value="Fish">Fish</option>
</select>
<?php if ($_POST['demo'] == 'Cat') { echo 'Miaow'; } ?>
However, in PHPFiddle,
I get 'E_NOTICE : type 8 -- Undefined index...'
as soon as the code runs. Am I missing something basic? Thanks!
Your form might be passing data by $_GET instead of $_POST.
Did you specify the method ?
<form method="post" action="index.php">
<select name="demo">
<option value="Dog">Dog</option>
<option value="Cat">Cat</option>
<option value="Fish">Fish</option>
</select>
<input type="submit" value="Submit">
</form>
You can var_dump($_POST); and var_dump($_GET); to see what those variables contains in your PHP file.
Or you can do it in javascript like this :
function animal(value) {
if(value == "Cat") {
document.getElementById("myAnimal").innerHTML = "Miaouw";
} else {
document.getElementById("myAnimal").innerHTML = "Rooooah";
}
}
<form action="#">
<select name="demo" onchange="animal(this.value)">
<option value="Dog">Dog</option>
<option value="Cat">Cat</option>
<option value="Fish">Fish</option>
</select>
</form>
<span id="myAnimal"></span>
Is it even possible to do this using PHP so that "Miaow" comes up automatically on select, rather than having to submit the form?
You are looking for JavaScript code, not PHP. Here is a jQuery example:
$(document).on('change', '.animals', function(){
$('.noise-target').html( $('option:selected', this).data('noise') );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="animals">
<option>Select</option>
<option data-noise="Woof">Dog</option>
<option data-noise="Meow">Cat</option>
</select>
<div class="noise-target"></div>
Maybe this will help, I write some block as far as I understand...
<form action="#" method="post">
<select name="demo">
<option value="Dog">Dog</option>
<option value="Cat">Cat</option>
<option value="Fish">Fish</option>
</select>
<input type="submit" name="sub" />
</form>
<?php
if(isset($_POST['sub'])){
if($_POST['demo'] == "cat"){
echo "Miao";
}
}
?>
I have this form:
<form name="summaryform">
<select name="category" id="category" style="width:500px;">
<option value="">Choose category...</option>
<option value="ActionScript">ActionScript</option>
<option value="AppleScript">AppleScript</option>
<option value="Asp">Asp</option>

<option value="Erlang">Erlang</option>
<option value="Fortran">Fortran</option>
<option value="Groovy">Groovy</option>
</select><br>
<select name="subcategory" id="subcategory" style="width:500px;">

<option value="JavaScript">JavaScript</option>
<option value="Lisp">Lisp</option>
<option value="Perl">Perl</option>
<option value="PHP">PHP</option>
<option value="Python">Python</option>
<option value="Ruby">Ruby</option>
<option value="Scala">Scala</option>
<option value="Scheme">Scheme</option>
</select><br>
<input type="text" name="comments" id="comments" value=" Enter request comments..." onfocus="clearText(this)" onblur="restoreText(this)" style="width:493px;color:#999;font-size:9pt;height:20px;">
On the form above, I have two dropdowns (name="categoryId" and "subcategoryid") and one textboxt (name="comments")
How do I pass the values from this form to another form?
Let's say below is the form I want to pass the values to:
<div>
<p>
<form name="summaryform" method='POST' action='process.php'>
<div style="font-size:12pt;">
value from one dropdown
value from the other dropdown
value from textbox
</form>
</p>
</div>
jQuery Method
If the forms are on the same page, you can use jQuery to get the values and write to the div:
var content = $('#category').val()+'<br>'+$('#subcategory').val()+'<br>'+$('#comments').val();
$('#div-to-write-to').html(content);
PHP Method
If the forms are on different pages, you will need to use PHP and the $_POST[] variable to pass the values you are looking for.
NOTE: for this method to work the page being POSTed to MUST be PHP. You will also need to add an action and method in the first form to POST to the second form.
This would be the code in the form on the page being POSTed to:
<?php echo $_POST['category'].'<br>'.$_POST['subcategory'].'<br>'.$_POST['comments']; ?>
A value can be passed between forms using the POST and GET methods. The first form (Which is sending the values) does not have this defined, so modify the first form to this -
<form name="summaryform" method='POST' action='process.php'>
Then, in process.php, put the following php code -
$dropdown_first = $_POST['category'];
$dropdown_second= $_POST['subcategory'];
$comment = $_POST['comments'];
After that, you can just use the variables as you see fit!
If you want just print the selected values from first form #zsaa14's
answer is good
If you want to print whole select list, autoselected your value, heres a code.
foreach($categories as $category) {
$selected = $category['name'] === $_POST['category'] ? 'selected="selected"' : '';
echo " <option value="{$category['name']}" {$selected}>{$category['name']}</option>" ;
}
NOTE: the variable names and keys are for example, use Yours. This is only fragment of code.
You can use post data fields to send the values to the next form
This question already has answers here:
Form action doesn't submit hard-coded variable
(3 answers)
Closed 9 years ago.
In the action attribute of my form element I have specified some get values, which will be sent along with the value from the actual form. However the values I have hardcoded in are not sent to the new document, what am I doing wrong?
<form action="loginForm.php?type=dept" method="get">
<select name="dept" onchange="this.form.submit()">
<option value="">Department</option>
<option value="Bar">Bar</option>
<option value="Cleaning">Cleaning</option>
<option value="Kitchen">Kitchen</option>
<option value="Management">Management</option>
<option value="Maintenance">Maintenance</option>
<option value="Waiting">Waiting</option>
</select>
</form>
At the top of the loginForm file is this code, which will output 'Type not set' every time
if(!isset($_GET['type']))
{
echo 'Type not set';
}
This is because the get parameters you are "forcing" by putting them in the URL are "overwritten" when the page is submitted. You will need to use a hidden field like:
input type="hidden" name="type" value="valuehere" />
Adding this to your form will submit this additional value.
Try to send it using hidden input like this : <input type='hidden' name='type' value='dept' />
Your code should be like this :
<form action="loginForm.php" method="get">
<input type='hidden' name='type' value='dept' />
<select name="dept" onchange="this.form.submit()">
<option value="">Department</option>
<option value="Bar">Bar</option>
<option value="Cleaning">Cleaning</option>
<option value="Kitchen">Kitchen</option>
<option value="Management">Management</option>
<option value="Maintenance">Maintenance</option>
<option value="Waiting">Waiting</option>
</select>
</form>
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>
http://jsfiddle.net/7xzKP/1/
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>
