Simple PHP select option programming - php

I have a simple problem in php select option.
The page has 5 select option & submit button. When I select a option then it should goes on specific web page. For Example: http://onlinetools.org/tricks/using_multiple_select.php
Then I select a option & press Send then It show Which option I select. But I need go specific webpage.
I have tried with this code but I have failed...
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
<select name="test[]" multiple="multiple">
<option value="http://google.com">one</option>
<option value="http://yahoo.com">two</option>
<option value="http://facebook.com">three</option>
<option value="http://who.is">four</option>
<option value="http://myspace.com">five</option>
</select>
<input type="submit" value="Send" />
</form>
<?php
$test=$_POST['test'];
echo "
<script type=\"text/javascript\">
window.location = \"$test\"
</script>
";
?>
Anybody Can help me?

This should be a simple select not a multiple one since you want to redirect to only one site. here is the code :
<?php
$test=$_POST['test'];
if(isset($test)){
header("Location: $test");
}
?>
<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
<select name="test">
<option value="http://google.com">one</option>
<option value="http://yahoo.com">two</option>
<option value="http://facebook.com">three</option>
<option value="http://who.is">four</option>
<option value="http://myspace.com">five</option>
</select>
<input type="submit" value="Send" />
</form>

As you've declared:
<select name="test[]" multiple="multiple">
test is an array, thus you have to take the first object of the array or remove the unused []. By the way, you can do an HTTP redirection, which is faster and works more often than javascript ones.

Get value of select, from a list of users

i have a table of users, where a user has a name, a surname, a right, and a "commit changes" button. This way, i want to assign rights to a person. Every column has the userID in it, and the whole thing is created from a database.
This is my dropdown to assign a right.
<form id="myForm" method="post" autocomplete="off">
<select name="rightsDropdownOptions" method="post">
<option value="admin">Admin</option>
<option value="masterEditor">MasterEditor</option>
<option value="modulEditor">ModulEditor</option>
<option value="teacher">Lehrer</option>
<option value="teacherAndEditor">Lehrer+Editor</option>
</select>
</form>
This is my php-code, which is executed by clicking the commitchangestorightsbutton
if ( isset($_POST['commitChangesOnRightsButton']) ){
$user = $_POST['commitChangesOnRightsButton'];
echo "<script>alert(".$user.");</script>";
$var = $_POST['rightsDropdownOptions'];
if($var == "1"){
echo "<script>alert(".$var.");</script>";
}
}
If i click the button now i get the following error:
Undefined index: rightsDropdownOptions in C:\xampp\htdocs\Iiigel\PHP\AdminGivePermission.php
I've been working on this for a while now, and i dont knwo how to solve this, id be glad if someone could help.
As highlighted by #Dharman you are making mistake in your code firstly you have to define post parameter "commitChangesOnRightsButton" into your code like this:
<form id="myForm" method="post" autocomplete="off" action"">
<select name="rightsDropdownOptions" method="post">
<option value="admin">Admin</option>
<option value="masterEditor">MasterEditor</option>
<option value="modulEditor">ModulEditor</option>
<option value="teacher">Lehrer</option>
<option value="teacherAndEditor">Lehrer+Editor</option>
</select>
<button type="submit" value="Assign" name="commitChangesOnRightsButton" />
</form>
Hope this will help!

Get selected option from html via php

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>

PHP: connect drop-down list with submit button and if/else statement

So, to explain my question. I have four .php codes on web server, and I have drop down list in php code also (it includes name of all four php files that are on server). I have also submit button.
I should do following: User choose one name from drop down list, click submit button, and than that php file should be called and shown on web page.
The problem is, I don't know hot to connect these three part of php code.

What Genre you want?
<select name="Ganre">
<option value="">Select...</option>
<option value="FPS">FPS</option>
<option value="JRPG">JRPG</option>
<option value="RPG">RPG</option>
<option value="Sports">Sports</option>
</select>
<input type="submit" value="Submit" />
<if (Genre == "FPS") { ?>
<form method="get" action="FPS.php"}>
<else if (Genre == "JRPG") { ?>
<form method="get" action="JRPG.php"}>
<else if (Genre == "RPG") { ?>
<form method="get" action="RPG.php"}>
<else if (Genre == "Sports") { ?>
<form method="get" action="Sports.php"}>
</p>
There are several issues with the code you provided:
You have no opening <?php for those closing ?>.
You have lots of invalid syntax, like If (Genre == "FPS") { (What is Genre?) or like
<else if
You have two spellings of "Genre" (Ganre).
There are several ways to do what you want. As you did not mention Javascript, I propose a PHP-only solution. You would just let the form submit to the
same PHP file, and there detect which choice was made. Then let PHP redirect to the
page of choice:
<?php
if (isset($_GET["genre"])) {
// User submitted their choice, so redirect to that page
// Make sure not to echo anything when using header():
header("Location: " . $_GET["genre"] . ".php");
// Make sure to not execute any other code in this file
exit();
}
// User did not yet submit a choice, so present list
?>
<form method="get">
<p>
What Genre you want?
<select name="genre">
<option value="">Select...</option>
<option value="FPS">FPS</option>
<option value="JRPG">JRPG</option>
<option value="RPG">RPG</option>
<option value="Sports">Sports</option>
</select>
<input type="submit" value="Submit"/>
</p>
</form>
Add onchange into select tag and add below javasctipt code.
<form method="get" action="">
<select name="Ganre" onchange="actionChangdde(this)">
<option value="">Select...</option>
<option value="FPS">FPS</option>
<option value="JRPG">JRPG</option>
<option value="RPG">RPG</option>
<option value="Sports">Sports</option>
</select>
<input type="submit" value="Submit" />
</form>
<script>
function actionChangdde(sel){
var getSelVal = sel.value;
var repAction = getSelVal+'.php';
sel.parentElement.setAttribute("action", repAction);
}
</script>
Try this code :
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
</head>
<form>
<p>
What Genre you want?
<select name="Ganre" id="genre">
<option value="">Select...</option>
<option value="FPS">FPS</option>
<option value="JRPG">JRPG</option>
<option value="RPG">RPG</option>
<option value="Sports">Sports</option>
</select>
<input type="submit" value="Submit" id="submit_button"/>
</p>
</form>
<script type="text/javascript">
$(document).ready(function(){
var dropDownValue = $('#genre').val();
$('#submit_button').click(function () {
if($('#genre').val() == "FPS"){
window.location="FPS.php";
}
if($('#genre').val() == "JRPG"){
window.location="JRPG.php";
}
if($('#genre').val() == "RPG"){
window.location="RPG.php";
}
if($('#genre').val() == "Sports"){
window.location="Sports.php";
}
if($('#genre').val() == ""){
return false;
}
});
});
</script>

Using select dropdowns in a form

I am trying to use HTML select dropdowns to help sort the search results on my website and I am having some trouble. In the code below, I specifically select Option1 and when I try to echo the result after I submit the form, it always echo's 'FAIL'. I was wondering if someone can help me understand what I am doing wrong and what is the proper way to retrieve the data from the option the user selected, after the form was submitted?
<?php
echo '<form method="post" action="search.php">
<select>
<option name="one">Option1 </option>
<option name="two">Option2</option>
</select>
<input type="text" name="searchword" />
<input type="submit" value="Search" />
</form>';
if(isset($_POST['one'])){
echo 'Option1 is set';
}else{
echo 'FAIL';
}
?>
thank you
This is because the name attribute goes with the select tag.
<select name="dropdown">
<option>Option 1</option>
<option>Option 1</option>
</select>
if(isset($_POST['dropdown'])) {
echo $_POST['dropdown']; //echoes 'Option 1'
}
If you like, you can add a value attribute to the option element, but you don't have to.
If you do
<option value="foobar">Option1</option>
The form will post foobar and not Option1.
<?php
echo '<form method="post" action="search.php">
<select name="my_option">
<option value="one">Option1 </option>
<option value="two">Option2</option>
</select>
<input type="text" name="searchword" />
<input type="submit" value="Search" />
</form>';
echo "My option value is : " . $_POST['my_option'];
?>
You need to name your select tag and access that instead.
<select name="options"></select>
echo $_POST['options']; will give you your selected option
Instead of name="one" an option needs a
value="myvalue"
and your select tag needs an
name="nameofthisthinghere"

HTML form submit to PHP script

I am making an HTML form. I want the results to appear in the PHP script.
<form action="chk_kw.php" method="post"> <br />
<select> name="website_string"
<option value="" selected="selected"></option>
<option VALUE="abc"> ABC</option>
<option VALUE="def"> def</option>
<option VALUE="hij"> hij/option>
</select>
<input type="submit" name="website_string" >
</form>
The problem is I cannot get the value passed to the PHP. if I use value:
<INPUT TYPE="submit" name="website_string" value="selected" >
It always passes the text in the quotes. In this case "selected". How do I pass one of the strings from the option?
Try this:
<form method="post" action="check.php">
<select name="website_string">
<option value="" selected="selected"></option>
<option VALUE="abc"> ABC</option>
<option VALUE="def"> def</option>
<option VALUE="hij"> hij</option>
</select>
<input TYPE="submit" name="submit" />
</form>
Both your select control and your submit button had the same name attribute, so the last one used was the submit button when you clicked it. All other syntax errors aside.
check.php
<?php
echo $_POST['website_string'];
?>
Obligatory disclaimer about using raw $_POST data. Sanitize anything you'll actually be using in application logic.
<form method="POST" action="chk_kw.php">
<select name="website_string">
<option selected="selected"></option>
<option value="abc">abc</option>
<option value="def">def</option>
<option value="hij">hij</option>
</select>
<input type="submit">
</form>
As your form gets more complex, you
can a quick check at top of your php
script using print_r($_POST);,
it'll show what's being submitted an the respective element name.
To get the submitted value of the element in question do:
$website_string = $_POST['website_string'];
It appears that in PHP you are obtaining the value of the submit button, not the select input. If you are using GET you will want to use $_GET['website_string'] or POST would be $_POST['website_string'].
You will probably want the following HTML:
<select name="website_string">
<option value="" selected="selected"></option>
<option value="abc">ABC</option>
<option value="def">def</option>
<option value="hij">hij</option>
</select>
<input type="submit" />
With some PHP that looks like this:
<?php
$website_string = $_POST['website_string']; // or $_GET['website_string'];
?>
Assuming you've fixed the syntax errors (you've closed the select box before the name attribute), you're using the same name for the select box as the submit button. Give the select box a different name.
For your actual form, if you were to just post the results to your same page, it should probably work out all right. Try something like:
<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?> method="POST>
Here is what I find works
Set a form name
Use a default select option, for example...
<option value="-1" selected>Please Select</option>
So that if the form is submitted, use of JavaScript to halt the submission process can be implemented and verified at the server too.
Try to use HTML5 attributes now they are supported.
This input
<input type="submit">
should be
<input name="Submit" type="submit" value="Submit">
whenever I use a form that fails, it is a failure due to the difference in calling the button name submit and name as Submit.
You should also set your enctype attribute for your form as forms fail on my web host if it's not set.
