I have a page with element <a> acting like a <button>, in this form the elements works like a service plans, and i want to get a value when one of these buttons has been clicked.
Page1.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Page 1</title>
<?php
session_start();
?>
</head>
<body>
<section>
Choose Plan1
<br><br>
Choose Plan2
<br><br>
Choose Plan3
</section>
</body>
</html>
Page2.php
<?php
session_start();
echo 'test';
echo $_POST['name'];
?>
I know that $_POST['name'] doesn't works cuz don't exist a input, but i don't know how use something like this to get a value of button clicked and show this value.
The return expected for first button for example, is something like:
basic
I need this value to put in database after.
Someone can help me to get this values?
You may pass the value as a url parameter
<section>
<a href="page2.php?plan=basic" >Choose Plan1</a>
<br><br>
Choose Plan2
<br><br>
Choose Plan3
</section>
And get it from $_GET in your php code
echo $_GET['plan'];

The question I'm trying to answer is below
Create a new PHP file named lab2.php.
Inside, add the HTML skeleton code and give its title “Lab Week 2"
Within the body tag, create a h1 tag that says "Enter the name of your favourite musical artist"
Add a section tag inside the body tag.
Create a form tag and use the $_GET method to get users to input their favorite artist. Store the user input into variables.
Create a submit button for the user to input their favorite artist.
Check whether the variable is empty or not.

i'm gonna hazard a guess and asume that this is some sort of educational task.
but nevertheless here is how i understand the tasks.

Now if this is some sort of test don't just copy of the internet. Do some fiddling around with the code and try to learn something :-)
I am trying to make an inex.php file as a dashboard page that shows a selection of files that are part of the folder that index.php is part of. and when the user selects the file, I want it to redirect to that page. I am using xammp as a local webserver for this.

<h1>Admin portal</h1>
<h3>select a php file relevent to a table in the database you would like to manage :index brings you right back :(</h3>
<form action="" method="POST">
<label for="pages">page:</label>
<select name="pages" id="page">
<?php
foreach (glob("*.php") as $filename) {
echo "<option value='strtolower($filename)'>$filename</option>";
}
?>
</select>
<br><br>
<input type="submit" value="Submit">
</form>
</body>
</html>
I am using a foreach to get all the files that are in the folder and populate them in a selection menu. I want to know how I can redirect to those files when I hit submit.
Your code is correct, you need only remove strtolower method from value, and use onchange on select tag.
Edit, Second Sol when submitted form :
<form action="" method="POST" onsubmit="return submitForm()">
<label for="pages">page:</label>
<select name="pages" id="page" >
<?php
foreach (glob("*.php") as $filename) {
$filename = strtolower($filename);
echo "<option value='$filename'>$filename</option>";
}
?>
</select>
<br><br>
<input type="submit" id='submitBtn' value="Submit">
</form>
<script type="text/javascript">
function submitForm(){
window.location.href = document.getElementById("page").value;
return false;
}
</script>
First sol,Try it:
<select name="pages" id="page" onchange=" (window.location = this.value);">
<?php
foreach (glob("*.php") as $filename) {
$filename = strtolower($filename);
echo "<option value='$filename'>$filename</option>";
}
?>
</select>
Don't use a select to redirect, use a <a> tag.

// edit: wrong concat operand
I am trying to create a option list , using a input field. The input field submits the data to my databse and in the same time i create a new file with the name of the value that i added in the input field and attach a exetension of ".php" to create a php file. Also together with the value i send also the file path into the database. In the index.php you can see the following code:
INDEX.PHP
<?php
include "conn.php";
$query="SELECT DISTINCTname,filePath FROM name_data";
$res=mysqli_query($conn,$query);
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<select name="select_list" id="list" onchange="location=this.value">
<?php foreach($res as $name){?>
<option value="<?php echo $name['filePath'];?>"><?php echo $name['name'] ;?></option>
<?php };?>
</select><br><br>
<form action="set.php" method="post">
<input type="text" name="name"><br><br>
<input type="submit" name="submit"><br><br>
</form>
</body>
</html>
And for the form submission i use the following code. Now in this example i dont use RegEx for the input field its just a simple code that i am trying:
SET.PHP
<?php
include "conn.php";
if(isset($_POST['submit'])){
$name=$_POST['name'];
$path=$name.".php";
$query="INSERT INTO name_data(name,filePath) VALUES('$name','$path')";
if(mysqli_query($conn,$query)){
header("LOCATION:index.php");
}
fopen($path,"w");
};
Now What i want to do, when i query the database i want the value(name) from the form submission to be linked to the corresponding file path(file Path) that i created during form submission.
How can I get an HTML value to send to PHP. I would like to avoid using a form. For example I have an input:
<input name="input" id="input">Input</input>
while in PHP:
$input = $_POST['input'] --> but didn't work
or
$input = $_GET['input'] --> still didn't work
I know that I will be able to get it using form then action="another file" but I want it within a file. Please help. Thank you.
If you simply want to use js to append the input value in url variable then you can use js function as follows;
client.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<input type="text" id="txt">
<a onclick="append()" id="anch" href="server.php?text">Send value</a>
</body>
</html>
<script>
function append()
{
txt=document.getElementById('txt');
anch=document.getElementById('anch');
anch.href=anch.href+"="+txt.value;
}
</script>
server.php
$variable = $_GET["input"];
echo $variable;
Output on localhost:
After clicking send value:-
Update: I just read the end of your question. If you want to show the value of input on same page/file then you can use following code;
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
</head>
<body>
<input type="text" id="txt">
<?php
if(isset($_GET['text']))
{
$text=$_GET['text'];
echo "<a onclick='append()' id='anch' href='?text=$text'>Enter Value</a>";
}
else
{
echo "<a onclick='append()' id='anch' href='?text'>Enter Value</a>";
}
?>
<br>
<?php
if(isset($_GET['text']))
echo "<div id='values'>".$_GET['text']."<div>";
?>
</body>
</html>
<script>
function append()
{
txt=document.getElementById('txt');
anch=document.getElementById('anch');
if(anch.href.match(/=/)=="=")
anch.href=anch.href+txt.value+"<br>";
else
anch.href=anch.href+"="+txt.value+"<br>";
}
</script>
Output:

It seems that the way to go is to use the GET method.
You will need to access your page with the get parameters included like this:
http://localhost/index.php?input=VALUE_HERE
And in your php file:
$variable = $_GET["input"];
echo $variable;
But if you insist to use inline html elements to get data, you need to use javascript for that like this for jquery:
alert("This is the value of the input" + $("#input").val());
Don't use this
<input name="input" id="input">Input</input>
Use this
<input name="input" id="input">
I want to add a variable Email address into the link (so email address dynamically fills when someone hit the link), which re-direct PHP. Email addresses are different based on person visited the link. So I am wondering, how can I in ordinary URL address add variable Email, which will then intervened and added to PHP re-direct?
This is the code, but not working...
<?PHP
$subid=$_GET[subid];
$email=$_GET[email];
?>
<html>
<head>
<meta http-equiv="refresh" content="0;url=http://xentrk.com/?a=41&c=308&s1={{ email|default:'null' }}<?PHP echo $subid;?>" />
</head>
<body>
You are using echo $subid in your URL:
Surely this should be $email ?
In which case this is the code:
<?php
$subid=$_GET['subid'];
$email=$_GET['email'];
?>
<html>
<head>
<meta http-equiv="refresh" content="0;url=http://xentrk.com/?a=41&c=308&s1={{ email|default:'null' }}<?php echo $email;?>" />
</head>
<body>
