I seem to be having trouble retrieving some values. For this PHP program, I have to store my first name, last name, phone number, a value for a radio button list, and a selecting a computer game from a select box/drop down list. What I have to do is store these values from the Ses1 file and retrieve them from the Ses2 file. At the moment, I can store all the 5 different values. When I hit the "Submit Information" button I can only retrieve the first name, last name, and telepehone number values. What can I do to retrieve the value from the radio button list and computer game from the drop down list. My current code down below.
<?php
// we always have to start session state
session_start();
if(isset($_POST["firstNameTextBox"]))
{
$_SESSION["firstName"] = $_POST["firstNameTextBox"];
header("Location: Session2.php");
}
if(isset($_POST["lastNameTextBox"]))
{
$_SESSION["lastName"] = $_POST["lastNameTextBox"];
header("Location: Session2.php");
}
if(isset($_POST["telephoneNumberTextBox"]))
{
$_SESSION["telephoneNumber"] = $_POST["telephoneNumberTextBox"];
header("Location: Session2.php");
}
if (isset($_POST["occupation"]))
{
$_SESSION["staff"] = $_POST["occupation"];
$_SESSION["sudent"] = $_POST["occupation"];
$_SESSION["faculty"] = $_POST["occupation"];
header("Location: Session2.php");
}
if(isset($_POST["games"]))
{
$_SESSION["League of Legends"] = $_POST["games"];
$_SESSION["Fallout 4"] = $_POST["games"];
$_SESSION["Overwatch"] = $_POST["games"];
$_SESSION["DOTA 2"] = $_POST["games"];
header("Location: Session2.php");
}

You need not store each radio button/select box options within the SESSION array.
Your SESSION array index should match the index of the POST array.
E.g: $_SESSION["occupation"] = $_POST["occupation"] instead of
`$_SESSION["staff"] = $_POST["occupation"];
$_SESSION["sudent"] = $_POST["occupation"];
$_SESSION["faculty"] = $_POST["occupation"];`
Try this:
if (isset($_POST["occupation"])) {
$_SESSION["occupation"] = $_POST["occupation"];
}
if (isset($_POST["games"])) {
$_SESSION["games"] = $_POST["games"];
header("Location: Session2.php");
}

I have just written this code in which I have a form. You have to write your name, surname and country. You also have to choose your favourite colour. After that, you push a submit button so that you can see the data afterwards. I'm using the GET method with 1 page, but I have to use a second one with the POST method so that each echo is on that second page.
How could I do that? My code is:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Form</title>
<link rel="stylesheet" type="text/css" href="form.css">
</head>
<body>
<section>
<?php
if (isset($_GET["name"])){
$name = $_GET["name"];
if ($name != ""){
$surname = $_GET["surname"];
$country = $_GET["country"];
$colour = $_GET["colour"];
echo "<p>";
echo "<h2>Data</h2>";
echo $name . " " . $surname . "</br />";
echo $country . "<br />";
echo $colour;
echo "</p>";
}else
echo "<strong>Complete the blank spaces</strong>";
}else{
?>
<h1>Form</h1>
<form class="elegant" method="GET" action="?">
<fieldset>
<legend>Favourite colour</legend>
<div>
<label for="nombre">Name</label>
<input type="text" placeholder="Name" name="name"
id="name" />
</div>
<div>
<label for="surname">Surname</label>
<input type="text" placeholder="Surname" name="surname"
id="surname" size="50" />
</div>
<div>
<label for="country">Country</label>
<input type="text" placeholder="Country" name="country" id="country"
size="10" maxlength="9" />
</div>
<div>
<select name="colour" id="colour">
<option value="yellow" <?php if ($colour == "yellow" ) echo "selected" ?> >yellow</option>
<option value="red" <?php if ($colour == "red" ) echo "selected" ?> >red</option>
</div>
<input class="btn" type="submit" value="Save" />
</fieldset>
</form>
<?php
}
?>
</section>
</body>
</html>
I know i have to use a link to that second page, but that's all I know. Thanks in advance!
If I understand correctly, the code you show is for Page 1 where the user can:
Input data if data don't exist;
View data and confirm them if they exist. At this point store data in SESSION and send the user to an other page.
To do so, remember you have to add the session_start() command right at the beginning of every page in which you will be able to manipulate Session Data.
<?php
session_start();
if (isset($_GET["name"])){
$name = $_GET["name"];
if ($name != ""){
$surname = $_GET["surname"];
$country = $_GET["country"];
$colour = $_GET["colour"];
echo "<p>";
echo "<h2>Data</h2>";
echo $name . " " . $surname . "</br />";
echo $country . "<br />";
echo $colour;
echo "</p>";
$_SESSION["name"] = $name;
$_SESSION["surname"] = $surname;
$_SESSION["country"] = $country;
$_SESSION["colour"] = $colour;
Confirm
}else
echo "<strong>Complete the blank spaces</strong>";
}else{
?>
...
In "another_page.php" then you will find that you can access your data simply querying the $_SESSION array.
<?php
session_start();
...
// Echo session variables that were set on previous page
echo "Name is " . $_SESSION["name"] . ".<br>";
echo "Surname is " . $_SESSION["surname"] . ".";
// etc.
?>
Complete reference is the PHP Manual and simple reference is in W3C PHP Sessions page.
In the form tag you can specify where to form gets submitted to:
<form class="elegant" method="GET" action="YOUR_PAGE_URL_HERE">
On that second page you get the values via the $_GET Variable like
<?php
echo $_GET['name'].' '.$_GET['surname'];
Im trying to save a variable in the $_Session[deptselect] and call it in a different page but confused to where to declare it. when i echo $_Session[deptselect] it gives blank.
I have already tried in multiple places like inside the form or below it but nothing seems to work. i want to send it from appointment to appointment2 but appointment2 seems to not get the variable.
I have already tried to use $_post[deptselect] to get the value in second page and i get it there but it disappears as soon as i press submit in the second page.
appointment.php
<?php
include("dbconnection.php");
session_start();
if(!isset($_SESSION['username'])) {
die("Please login");
}
$_SESSION['deptselect']=$_POST['deptselect'];
?>

$deptsql=mysqli_query($con,"select deptname,deptid from department where status='1'");
while ($row = mysqli_fetch_assoc($deptsql))
{
echo "<option id='deptselect' value='" . $row['deptid'] ."'>" . $row['deptname'] ."</option>";
}
?>
</select>

<input type="submit" name="submit" value="Submit">
</form>
</body>
<?php include("footer.php");
?>
I want the $_session[deptselect] in appointment2.php so i can run the command the insert, i have zero knowledge of js so doing the dependent list thing is not possible. TIA
In the beginning of the first script you have:
if(!isset($_SESSION['username'])) {
die("Please login");
}
And in the beginning of the second:
if(!isset($_SESSION['username']))
{
include('footer.php');
die("Please login");
}
Both stop immediately, if $_SESSION['username'] is not set.
So how should $_SESSION['username'] ever be set, if your body code is never executed?
I want a first radio button to be checked by default. When I click get schedule I want to fetch the schedule of that radio selected train number using a WHERE clause.
<?php
while ($res = mysql_fetch_array($result)) {
echo "<tr>";
echo "<td><input type = radio />" . $res['Train_no'] . "</td>";
?>
<form action="schedule.php" method="POST" class="form-inline">
<input type="submit" value="Get Schedule"/>
</form>
<?php
}
<?php
$con = mysql_connect("localhost", "root", "");
if ($con) {
$db = mysql_select_db('traindb', $con);
} else {
die('Could not connect: ' . mysql_error());
}
$selected_val = $_POST['Train_no']; // Storing Selected Value In Variable
echo "You have selected :" . $selected_val; // Displaying Selected Value
$result = mysql_query("SELECT * FROM train_detail WHERE Train_No='$selected_val'");
mysql_close($con);
?>
You can try this:
if(isset($_POST['Submit'])){
$selected_val = $_POST['Train_no']; // Storing Selected Value In
echo "You have selected :" .$selected_val; // Displaying Selected Value
$result = mysql_query("SELECT * FROM train_detail WHERE
Train_No='$selected_val'");
}
Here is one example of "select":
<form action="" method="post">
<select type="age" class="form-control" id="age" name="age">
<!-- <option value="disable" selected="">Please Select</option> -->
<option value="">Please select</option>
<option value="Under 35">Under 35</option>
<option value=">35 - 44">35 - 44</option>
<option value=">45 - 54">45 - 54</option>
<option value=">55 - 59">55 - 59</option>
<option value=">60 - 64">60 - 64</option>
<option value=">65 - 69">65 - 69</option>
<option value=">70 - 74">70 - 74</option>
<option value=">75 - 79">75 - 79</option>
<option value="80 +">80 +</option>
</select>
<input type="submit" value="Submit">
</form>
<?php
$age = $_POST['age'];
if (isset($_POST['age']) && $_POST['age'] == "")
echo "You did not choose any options. Pls try again.";
else {
echo $age;
}
?>
If you want embed PHP in select options, do it like this:
<option value="<?php echo $res['Train_no'] ?>"><?php echo $res['some_other'] ?></option>
For radio button it is like this:
<!DOCTYPE html>
<html>
<body>
<form action="/action_page.php">
<input type="radio" name="gender" value="<?php echo $res['Train_no'] ?>" checked><?php echo $res['some_other'] ?><br>
<input type="radio" name="gender" value="female"> Female<br>
<input type="radio" name="gender" value="other"> Other<br><br>
<input type="submit">
</form>
</body>
</html>

I am wanting to replace the status text filed with a drop down list of options.
Replace your <input by <select :
<form action="" method="post">
<input type="hidden" name="id" value="<?php echo $id; ?>"/>
<div>
<p><strong>ID:</strong> <?php echo $id; ?></p>
<strong>School Name:</strong> <input type="text" name="Name" value="<?php echo $Name; ?>"/><br/><br>
<!-- <strong>Status:</strong> <input type="text" name="Status" value="<?php echo $Status; ?>"/><br/><br>-->
<strong>Status:</strong> <select name="Status">
<option value="1">Status 1</option>
<option value="2">Status 2</option>
</select>
<strong>Comments:</strong> <input type="text" name="Comments" value="<?php echo $Comments; ?>"/><br/><br>
<strong>Type:</strong> <input type="text" name="Type" value="<?php echo $Type; ?>"/><br/><br>
<input type="submit" name="submit" value="Submit">
</div>
</form>
If your statuses are in a table, fill the <select> with a query :
<form action="" method="post">
<input type="hidden" name="id" value="<?php echo $id; ?>"/>
<div>
<p><strong>ID:</strong> <?php echo $id; ?></p>
<strong>School Name:</strong> <input type="text" name="Name" value="<?php echo $Name; ?>"/><br/><br>
<!-- <strong>Status:</strong> <input type="text" name="Status" value="<?php echo $Status; ?>"/><br/><br>-->
<strong>Status:</strong> <select name="Status">
<?php
$result = mysql_query("SELECT * FROM tbl_status",$cnx);
while ( $row = mysql_fetch_array($result) )
echo "<option value='" . $row["id"] . "'>" . $row["text"] . "</option>";
?>
</select>
<strong>Comments:</strong> <input type="text" name="Comments" value="<?php echo $Comments; ?>"/><br/><br>
<strong>Type:</strong> <input type="text" name="Type" value="<?php echo $Type; ?>"/><br/><br>
<input type="submit" name="submit" value="Submit">
</div>
</form>
You could use the html <datalist> or the <select> tag.
I hope I could help.
First of all you need to switch from mysql_* to mysqli_* as it going to get removed in php 7.0 I'm using this function i created and it might help you
here is the php code
function GetOptions($request)
{
global $con;
$sql = "SELECT * FROM data GROUP BY $request ORDER BY $request";
$sql_result = mysqli_query($con, $sql) or die('request "Could not execute SQL query" ' . $sql);
while ($row = mysqli_fetch_assoc($sql_result)) {
echo "<option value='" . $row["$request"] . "'" . ($row["$request"] == $_REQUEST["$request"] ? " selected" : "") . ">" . $row["$request"] . "$x</option>";
}
}
and the html code goes like
<label>genre</label>
<select name="genre">
<option value="all">all</option>
<?php
GetOptions("genre");
?>
</select>
I found this site providing code for creating, reading, updating and deleting. I am confused about how to add checkboxes, radio buttons, and dropdowns
http://www.killersites.com/community/index.php?/topic/1969-basic-php-system-vieweditdeleteadd-records/
I'm not concerned with the pagination at all——my primary concern is to be able to put in two dropdowns, yes/no radio button, and a collection of 3 checkboxes using PHP.
My attempts were useless as when I tried to edit choices the values did not stay. Included are my three files: pets, editpets, and view.(I changed the file name for database, etc.)

I'm honestly lost at this point. I've been working on this for an entire month and I have no idea what I'm doing any more. I'd be so thankful if anyone can help me to edit this to work.
Thanks everyone.
Right, to get your saved results from the database I'm sure you're aware of how to do this.
For your radio buttons you're going to want to select your 'size' value from the database and use an if statement to determine which radio button will be 'checked'
forename/surname is a matter of simply getting the forename/surname from database and setting the appropriate input tags to the acquired values
You've already posted a technique for handling the combo/drop-down boxes
you'd perform a similar process for the 'type' checkboxes, compare your database values to the values of your checkbox input tags and if the value matches, set the checkbox to checked.
Next time please be more specific in what you are asking for help with and separate your code into segments that correspond with the files it is contained in.
if you have 3 files, have a code block for each file.
