I have a php code that take values from a form and add them into MySQL database.
First part of the PHP code, see if the admin choose an already exist patient from drop list, then add a date and time of an appointment with a reason.
Then values are posted into PHP code where we see if we have already an appointment in those date and time. If not ($appExistStmtCount == 0) then go and insert an appointment.
The problem is that nothing added to database and can't see any PHP errors echoed.
Here is the PHP code:
<?php
//Set error reporting on
error_reporting(E_ALL);
ini_set("display_errors", 1);
//Include connection file
require_once('../include/global.php');
$user = $_SESSION['username'];
$id_logged = $_SESSION['login_id'];
if(isset($_POST['add_app_btn'])){
//Values From AJAX
$patient_name = $_POST['patient_name'];
$date_app = $_POST['app_date'];
$time_app = $_POST['app_time'];
$reason = $_POST['app_reason'];
$old_patient_id = $_POST['select_old'];
//If new patient
if($patient_name == "" && $old_patient_id != "choose")
{
try{
//See if date and time exist
$appExist = "SELECT * FROM appointment WHERE id_logged = :id_logged AND date_app = :date_app and time_app = : time_app";
$appExistStmt = $conn->prepare($appExist);
$appExistStmt->bindValue(":id_logged", $id_logged);
$appExistStmt->bindValue(":date_app", $date_app);
$appExistStmt->bindValue(":time_app", $time_app);
$appExistStmt->execute();
$appExistStmtCount = $appExistStmt->rowCount();
if($appExistStmtCount == 0)
{
//Add to appointment table
$appAdd = "INSERT INTO appointment(id_logged, patient_id, date_app, time_app, reason)
VALUES(:id_logged, :patient_id, :date_app, :time_app, :reason)";
$appAddStmt = $conn->prepare($appAdd);
$appAddStmt->bindValue(":id_logged", $id_logged);
$appAddStmt->bindValue(":patient_id", $old_patient_id);
$appAddStmt->bindValue(":date_app", $date_app);
$appAddStmt->bindValue(":time_app", $time_app);
$appAddStmt->bindValue(":reason", $reason);
$appAddStmt->execute();
echo "added";
}
else
{
echo "not added";
header("Location: add_appoint.php");
}
}
catch(PDOException $m)
{
$m->getMessage();
echo "error";
header("Location: add_app_btnoint.php");
}
}
}
?>
And here the HTML form:
<form class="form-horizontal" id="add_app_form" onSubmit="return validate(this);">
<div class="box-body">
<div class="form-group">
<label for="patient_name" class="col-sm-3 control-label">Old Patient</label>
<div class="col-sm-4">
<select id="select_old" name="select_old">
<option value="choose">Choose Name</option>
<?php foreach($name_array as $na) { ?>
<option value="<?php echo $na['id'] ?>"><?php echo $na['patient_name'] ?></option>
<?php } ?>
</select>
</div>
<label for="patient_name" class="col-sm-1 control-label">New</label>
<div class="col-sm-4">
<input type="text" class="form-control" id="patient_name" name="patient_name" placeholder="New Patient Name">
</div>
</div>
<div class="form-group">
<label for="app_date" class="col-sm-2 control-label">Date</label>
<div class="col-sm-4">
<input type="date" class="form-control" id="app_date" name="app_date">
</div>
<label for="app_time" class="col-sm-2 control-label">Time</label>
<div class="col-sm-4">
<input type="time" class="form-control" id="app_time" name="app_time">
</div>
</div>
<div class="form-group">
<label for="app_reason" class="col-sm-2 control-label">Reason</label>
<div class="col-sm-10">
<textarea class="form-control" id="app_reason" name="app_reason" placeholder="Reason"></textarea>
</div>
</div>
</div><!-- /.box-body -->
<div class="box-footer">
<button type="submi;" id="add_app_btn" class="btn btn-success pull-right">Add Appointment</button>
</div><!-- /.box-footer -->
</form>
PS
Values can be seen in the URL but the page just refresh and nothing added

Answer 1

Your form has no method, so it's passing data through get. You need to add method="post" to your form.
Edit. As #u_mulder mentioned, you need to add name attribute to your button for the check in your php if the button is clicked.
