I am new to this form and to php. I have got this code but always I got these errors.
Notice: Undefined index: id
Notice: Undefined index: name
Notice: Undefined index: remarcs
Notice: Undefined index: test_res
Notice: Undefined index: date
Notice: Undefined index: phone_num

I have this html code of the form:
<form action="/clinic form/insert/insert.php" id="Form2" method="POST" enctype="multipart/form-data" class="c">
<div align="center">
<?php echo "Insert information about a new Patient "?>
<table class="imagetable" border="1" cellspacing="3" align="center">
<th>Personal Informations</center></th>
<th>Test Results</th>
<tr><td>Name<br>
<input type="text" class="large-fld" name="name" placeholder="Patient Name"></td>
<td>Remarcs:<br>
<textarea type="text" cols="40" rows="5" class="large-fld" name="remarcs" placeholder="Remarcs"></textarea></td>
<tr><td>Address<br>
<input type="text" class="large-fld" name="address" placeholder="Address"/>
</td>
<td>Test<br> <textarea type="text" cols="40" rows="5" class="large-fld" name="test_res" placeholder="Test Result"></textarea></td></tr>
</td>
</tr>
<tr><td>Phone Number<br>
<input type="text" class="large-fld" name="phone_num" placeholder="Phone Number"/>
</td>
<th>Files</th>
</tr>
<td>Date<br>
<input type="text" class="large-fld" name="date" id="date" placeholder="0000-00-00"/></td>
<td>Echo Files:<br>
<input type="file" name="file" id="file"/><br></td>
</tr></th></table>
<div class="row" align="center">
<input type="image" name="login" value="Login" src="images/insert.png" width="widthInPixels" height="heightInPixels" onMouseOver="this.src='images/insertRoll.png';" onMouseOut="this.src='images/insert.png';"> </td></tr>
</table></div>
</form>
And this html code that I found it online:
<?php
require_once ('../include/global.php');
$name = '';
$remarcs = '';
$address = '';
$test_res = '';
$date = '';
$phone = '';
$new_path = '';
if(isset($_POST['submit'])){
if (isset ($_POST['name'])) {
$name = $_POST['name'];
}
if (isset ($_POST['remarcs'])) {
$remarcs = $_POST['remarcs'];
}
if (isset ($_POST['test_res'])) {
$test_res = $_POST['test_res'];
}
if (isset ($_POST['address'])) {
$address = $_POST['address'];
}
if (isset ($_POST['date'])) {
$date = $_POST['date'];
$desiredFormat = date('d/m/Y', strtotime($date));
}
if (isset ($_POST['phone_num'])) {
$phone = $_POST['phone_num'];
}
$path = "../uploads/".$_FILES['file']['name'];
//$path2 = "../uploads/".$_FILES['echo_photo']['name'];
$ext = pathinfo($path, PATHINFO_EXTENSION);
//if(move_uploaded_file($_FILES["file"]["tmp_name"], $path.'_'.time().date().$_FILES['file']['name'])){
move_uploaded_file($_FILES["file"]["tmp_name"], $path.'_'.time().date().'.'.$ext);
$new_path = "./uploads/".$path.'_'.time().date().'.'.$ext;
$sql="INSERT INTO patients (name, echo_files, remarcs, test_res, date, address, phone_num)
VALUES
('$name', '$new_path', '$remarcs', '$test_res', '$desiredFormat', '$address', '$phone')";
$result=mysqli_query($con,$sql) or die('Unable to execute query. '. mysqli_error($con));
if($result){
/*echo $name."<p>\n</p>";
echo $remarcs."<p>\n</p>";
echo $test_res."<p>\n</p>";
echo $address."<p>\n</p>";
echo $phone."<p>\n</p>";*/
header("location:insert_done.php");
} else {
header("location:insert_false.php");}
}
?>
Can someone tells me what is wrong with this code ?

Answer 1

Its because, you are trying to get $_POST ed variables before form submit.
Try this:
if (isset($_POST['YOUR_SUBMIT_BUTTON']) {
$remarcs = $_POST['remarcs'];
// Your other variables which are posted.
// Place all your code you need to execute after form submit.
}
Another thing is that you are using date as one of your field.
It is a reserved keyword in MySQL.
You should enclose it with backtick (`) to avoid conflict.
Corrected Code:
<?php
require_once ('../include/global.php');
$name = '';
$remarcs = '';
$address = '';
$test_res = '';
$date = '';
$phone = '';
$new_path = '';
if (isset($_POST['submit'])){
$name = isset($_POST['name']) ? $_POST['name'] : '';
$remarcs = isset($_POST['remarcs']) ? $_POST['remarcs'] : '';
$test_res = isset($_POST['test_res']) ? $_POST['test_res'] : '';
$address = isset($_POST['address']) ? $_POST['address'] : '';
$phone_num = isset($_POST['phone_num']) ? $_POST['phone_num'] : '';
$date = isset($_POST['date']) ? $_POST['date'] : date('d/m/Y', strtotime($date));
$path = "../uploads/".$_FILES['file']['name'];
$ext = pathinfo($path, PATHINFO_EXTENSION);
//if(move_uploaded_file($_FILES["file"]["tmp_name"], $path.'_'.time().date().$_FILES['file']['name'])){
move_uploaded_file($_FILES["file"]["tmp_name"], $path.'_'.time().date().'.'.$ext);
$new_path = "./uploads/".$path.'_'.time().date().'.'.$ext;
$sql="INSERT INTO patients (name, echo_files, remarcs, test_res, `date`, address, phone_num)
VALUES
('$name', '$new_path', '$remarcs', '$test_res', '$desiredFormat', '$address', '$phone')";
$result=mysqli_query($con,$sql) or die('Unable to execute query. '. mysqli_error($con));
if($result){
header("location:insert_done.php");
}
else {
header("location:insert_false.php");
}
}
?>
