Submit value on GET - php

OK, this is probably elementary, but I'm having a mental block.
I have a set of radio buttons and I need to submit the value to a URL in the following format:
mypage/myValue
and not
mypage/?name=myValue
Here's what I have:
<form action="mypage/" method="get">
<input type="radio" name="name" value="myValue_1"> label 1
<input type="radio" name="name" value="myValue_2"> label 2
<input type="radio" name="name" value="myValue_3"> label 3
<input type="submit">
</form>
Perhaps I'm overthinking but my initial reaction is to form the URL with jQuery on click, and than just redirect... Sounds a bit too much, isn't it?

It shouldn't be mush code (jQuery) if it's only the radios - something like:
<form>
<input type="radio" name="rname" value="myValue_1"> label 1
<input type="radio" name="rname" value="myValue_2"> label 2
<input type="radio" name="rname" value="myValue_3"> label 3
<input type="button" id="btncl">
</form>
and in the script:
$("#btncl").click(function(){
window.location="mypage/"+$('input[name=rname]:radio:checked').val();
});
Otherwise, I don't think there is a way of doing it with regular html, since the standards say that GET is ...?name=val&n2=v2....
The server side redirection should be more time-consuming (for both writing and using)

HTML/CSS/PHP Hide Form Values with Radio Buttons

I was trying to make multiple options for a sign-in form. I want my form to have two options, either sign in by username or sign in by email. I want to use radio buttons for the user to select which method they choose to sign in. I was wondering if there is a way with html/css/php to do this or if I must learn to use something else? I am not seeing any examples of this.
Here are some visuals with examples of what I am wanting:
By default I want it to look like this:
When Radio buttons are selected, I want it to look like this:
My current code just looks something like this (this is my code with both text boxes)
<form method='post'>
<input type="radio" name="reason" value="email">Login with Email<br> <input type="text" name="email_text"/><br>
<input type="radio" name="reason" value="user">Login with Username<br> <input type="text" name="user_text"/><br>
<button type="submit" class="btn btn-primary">Login</button>
</form>
You can pretty much do this just with some simple CSS that makes use of a sibling selector and the :checked attribute combined. You can't select a previous element but you can select the following element using +
input[type='text'],
input[type='password']{display:none}
:checked + input{display:block;}
<form method='post'>
<input type="radio" name="reason" value="email">Login with Email
<input type="text" name="email_text"/>
<br />
<input type="radio" name="reason" value="user">Login with Username
<input type="text" name="user_text"/>
<br />
<button type="submit" class="btn btn-primary">Login</button>
</form>

HTML Form - Input Type hidden with PHP post input not working

Clarification:
I have a form let say like this:
<form method="post" action="https://www.example.at/example/" id="comparison">
<input type="radio" id="region" name="region" value="austria">
<input type="radio" id="region" name="region" value="germany">
<input type="radio" id="tarif" name="tarif" value="Basis">
<input type="radio" id="tarif" name="tarif" value="Comfort">
<input type="submit" name="submit" value="compare">
</form>
User can submit - working finely.
On a second page (https://www.example.at/example/) I want to pick up the variable region. But I would like the user to again be able to switch between Basis and Comfort. So value region does not to be entered again.
<form method="post" id="comparison2">
<input type="hidden" name="region" id="region" value="<?php echo_POST['region']; ?>" />
<input type="radio" id="tarif" name="tarif" value="Basis">
<input type="radio" id="tarif" name="tarif" value="Comfort">
<input type="submit" name="submit" value="compare">
</form>
So if I echo the php with region it gives me the correct value outside of the form. Altough after submitting the second form it triggers a php shortcode(again) with the submit again where it displays a € value from our database.
But even though it worked properly with the input entered by the user(first step) it doesn't use or differently use the hidden input.
If it helps: I'm currently testing here: https://www.krankenversichern.at/testing-environment/
So the solution was: I took all of my html code and put it in a shortcode. I used the php echo as suggested and used the text element widget in elementor. That's it. Took probably 2 minutes!

php comparison of values in two radio buttons

this is one radio button set
<input type="radio" name="image" id="100" value="a"/>
<input type="radio" name="image" id="100" value="b"/>
<input type="radio" name="image" id="100" value="c"/>
<input type="radio" name="image" id="200" value="d"/>
<input type="radio" name="image" id="200" value="e"/>
<input type="radio" name="image" id="300" value="f"/>
<input type="radio" name="image" id="300" value="g"/>
<input type="radio" name="image" id="400" value="h"/>
and so on...
and this is another radio button set
<input type="radio" name="number" value="100"/>
<input type="radio" name="number" value="200"/>200
<input type="radio" name="number" value="300"/>300
<input type="radio" name="number" value="400"/>400
<input type="radio" name="number" value="500"/>500
<input type="radio" name="number" value="600"/>600
my question is how can i compare value of one with value="100" to other with id="100" in php
there is a comparison i want to make but for the field with id = 100 i have values as abcd.. so i cant assign it value = 100 cuz i m saving it in database
means..
there are other fields with id=100 but their values shall be diffrent otherwise i m not able to identify them after they are send to databse
still i have to do comparison of both.. and that too serverside
so what are my options?
more detailed explanation....
there are two sets of radio buttons..
in one set there are values..
and in other sets there are images related to those values..
when user clicks set of value... and user click on set of images
so php shall match that image to the value.. if user clicked on 100 as value and later he clicks on an image under the id 200
database shall not allow it to enter and gave him some error
Sorry Had to see what your talking about. Help to edit this so to understand your requirement, 'shall match that image to the value'
<input type="radio" name="image" class="100" value="a_100"/>
<input type="radio" name="image" class="100" value="b_100"/>
<input type="radio" name="image" class="100" value="c_100"/>
<br>
<input type="radio" name="number" value="100"/>
<input type="radio" name="number" value="200"/>
<input type="radio" name="number" value="300"/>
<?php
$image = strstr($_POST['image'],'_');
$number = '_'.$_POST['number'];
if($image == $number) {
//Do something
}
The question is looking for to compare the two fields in PHP. Presumably this means that you want to examine them when the form is posted.
This means that you'll only have available to you the parts of the field that are sent via the POST -- ie the field name and the value. PHP will never see the id of any of the fields, nor the class, nor any other attributes in the HTML code other than name and value.
Therefore the discussion in the comments about whether or not to use id is a somewhat moot point -- even if it is a good point for you to know in general for your HTML code, you can't really use either id or class here anyway because PHP will never see them.
You need to take an entirely different approach.
[EDITED after question edit]
Add the 100 or 200, etc to the value of the image radio buttons, like so:
<input type="radio" name="image" value="a_100"/>
<input type="radio" name="image" value="b_100"/>
<input type="radio" name="image" value="c_100"/>
<input type="radio" name="image" value="d_200"/>
<input type="radio" name="image" value="e_200"/>
<input type="radio" name="image" value="f_300"/>
<input type="radio" name="image" value="g_300"/>
<input type="radio" name="image" value="h_400"/>
(The number radio button set remains unchanged from your question)
You can then read it in PHP as follows:
$number = $_POST['number'];
list($imgNumber, $imgValue) = explode('_',$_POST['image']);
You can now compare $number with $imgNumber.
Hope that helps.
It's worth asking a follow-up question though: What are you trying to achieve here? Is this a validation exersise? ie where you're checking that the user is selecting an image option that matches the number option he's picked? If that's what you're doing, you may find it's more user friendly to use Javascript to filter the options available when they select the number option so that the image radio button set only shows options that are valid for the selected number.
This would be an entirely different question, so I won't go into any detail here, but I would suggest that it might be a more user-friendly way of doing things if you did it like that.

PHP post variables titles

I am wondering how I can extract the title variable from my forms posted fields array.
I know $_POST['name'] is the field name but can I do something like $_POST[title] to get the title?
I ask because I have a dynamic form with variable lengths. The dynamics is group_one contains 5 fields, group_two contains 12 fields, group_three contains 2 fields for example.
I am hoping to loop through these groups and post the title of the form field to a column in a DB and its value. Any help appreciated with understanding if I can use the 'title' variable in the form field element.
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesYes" value="Yes" title="Dog at premises" />Yes
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesNo" value="No" title="Dog at premises" />No
<input type="text" name="txtGroupOne[]" id="txtNextOfKinName" title="Next of kin name" />
<input type="text" name="txtGroupOne[]" id="txtNextOfKinContact" title="Next of kin contact" />
No, only the name="x" attribute is sent by default in an HTML Form. title="x" is not sent. You can technically get around it with some crazy Javascript and an Ajax POST, but I would avoid that if I were you.
What do you want the title sent to your server side for? There surely probably a better alternative to achieve your goal.
You can add hidden field to each of fields that need titles to be sent to server besides their values.
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesYes" value="Yes" />
<input type="hidden" name="txtGroupOneTitles[]" value="Dog at premises" >
<input type="radio" name="txtGroupOne[]" id="txtDogAtPremisesNo" value="No" />
<input type="hidden" name="txtGroupOneTitles[]" value="Dog at premises" >
<input type="text" name="txtGroupOne[]" id="txtNextOfKinName" />
<input type="hidden" name="txtGroupOneTitles[]" value="Next of kin name" >
<input type="text" name="txtGroupOne[]" id="txtNextOfKinContact" />
<input type="hidden" name="txtGroupOneTitles[]" value="Next of kin contact" >
You can do something like this:
foreach($_POST as $form_var){
// Compile your code here, etc.
}
Anything that does not have a "name" attribute in your form will not be part of the $_POST array.
ie,
<input type='text' id='bar'>
<input type='text' name='foo' id='foo'>
Only $_POST['foo'] would exist.
Misread the question slightly, but you could also prepend your input names to include the "group title" upon generation.
<input type='text' name='title1_foo' id='title1_foo'>
Then you can manipulate the information you want from the $_POST loop.

Only allowing selection of one radio button in a form with PHP

A very basic question...
How can I only allow the selection of one option in a list of radio buttons?
<form action="process_repair.php" method="POST">
<label for "repair_complete">Repair complete</label>
<input type="radio" name="Yes" value="true">
<input type="radio" name="No" value="false">
</form>
When this code runs, it's possible to select both radio buttons, but I'd like them to interact so you can only select one or the other.
Any help much appreciated! :)
Give them the same name.
<form action="process_repair.php" method="POST">
Repair complete
<input type="radio" name="complete" value="true" id="complete_yes" />
<label for="complete_yes">Yes</label>
<input type="radio" name="complete" value="false" id="complete_no" />
<label for="complete_no">No</label>
</form>
Labels must have a for attribute, directing to the corresponding input's id.
Every input should have same "name"
