EDIT
Ive now got the following - but still it does not work
<script>
$(document).ready(function() {
$("button").click(function(){
var jsPostcode = document.login.getElementsByName("postcode").value;
var jsEmail = document.login.getElementsByName("email").value;
var formdata = {postcode:jsPostcode,email:jsEmail};
$.ajax(
{
type: "POST",
url: "database.php", //Should probably echo true or false depending if it could do it
data : formdata,
success: function(feed) {
if (feed!="true") {
// DO STUFF
} else {
console.log(feed);
// WARNING THAT IT WASN'T DONE
}
}}}};
</script>
=================================================================
ORIGINAL QUESTION FOLLOWS
I'm trying to take in data using a form and send some of this to a Mysql database. I cant use the action keyword in the form as that is being used to complete authentication therefore I am trying to use ajax and jquery. I have got to a point where I know I am close to cracking it but I'm not sure what is wrong. Please see my files below. First off the main file login.php is below:
Form Follows (login.php)
<?php
$mac=$_POST['mac'];
$ip=$_POST['ip'];
$username=$_POST['username'];
$linklogin=$_POST['link-login'];
$linkorig=$_POST['link-orig'];
$error=$_POST['error'];
$chapid=$_POST['chap-id'];
$chapchallenge=$_POST['chap-challenge'];
$linkloginonly=$_POST['link-login-only'];
$linkorigesc=$_POST['link-orig-esc'];
$macesc=$_POST['mac-esc'];
if (isset($_POST['postcode'])) {
$postcode = $_POST['postcode'];
}
if (isset($_POST['email'])) {
$email = $_POST['email'];
}
?>
**SOME HTML HERE**
<script src="jquery-3.2.1.min.js"></script>
<script>
var js-postcode = document.login.getElementsByName("postcode").value;
var js-email = document.login.getElementsByName("email").value;
var formdata = {postcode:js-postcode,email:js-email};
$("button").click(function(){
$.ajax(
{
type: "POST",
url: "database.php", //Should probably echo true or false depending if it could do it
data : formdata,
success: function(feed) {
if (feed!="true") {
// DO STUFF
} else {
console.log(feed);
// WARNING THAT IT WASN'T DONE
}
}}}
</script>

}

So I try enter value for client ic, for example 1234, there is no data in the database that match the value that i entered just now but the result still show have, can i know why because i already don't have way to solve this
Thatś because when you use wildcards LIKE '%".$query."%' if your variable $query is empty you are just getting all because you compare with everything LIKE '%%'.
You need to change this sentence:
$raw_results = mysql_query("SELECT * FROM client WHERE ('client_name' LIKE '%".$query."%') OR ('client_ic' LIKE '%".$query2."%') OR ('client_add_1' && ' ' && 'client_add_2' && ' ' && 'client_add_3' && ' ' && 'client_add_4' LIKE '%".$query3."%')") or die(mysql_error());;
whith something like this
$sql_query="SELECT * FROM client WHERE ";
$other=false;
if ($query != null and $query!="") {
$sql_query=$sql_query."('client_name' LIKE '%".$query."%')";
$other=true;
}
if ($query2 != null and $query2!="") {
if ($other) {
$sql_query=$sql_query." OR ";
}
$sql_query=$sql_query."('client_ic' LIKE '%".$query2."%')";
$other=true;
}
if ($query3 != null and $query3!="") {
if ($other) {
$sql_query=$sql_query." OR ";
}
$sql_query=$sql_query."('client_add_1' && ' ' && 'client_add_2' && ' ' && 'client_add_3' && ' ' && 'client_add_4' LIKE '%".$query3."%')";
$other=true;
}
if ($other) {
$raw_results = mysql_query($sql_query) or die(mysql_error());
}
<script>
function removeAllRowsContainingCheckedCheckbox() {

var row= table.rows[rowi];
var inputs= row.getElementsByTagName('input');
for (var inputi= inputs.length; inputi-->0;) {
//alert("inside for");

For the submit can i able to write javascript function with out using
$checkbox1=$_POST['techno'];
$chk="";
foreach($checkbox1 as $chk1)
{
$chk .= $chk1."";
echo '<script>alert("Inserted Successfully")</script>';
}
above code because if(isset($_POST['sub'])) is reloading the already submitted checkboxs in the table so user may confuse after delete the page will again show all the check box those who are submitted also .. Please suggest alternatives for this any ways i want to insert the checked checkboxes into database but my thought is to delete the checked submitted also in the table.
I have the following javascript being included in some PHP which I am writing. The problem is that it is not working and developer tools keeps saying "'validate_entry' is undefined" but I don't know what I'm doing
My code is:
<script type="text/javascript">
function validate_entry()
{
var name=document.getElementById("submitted").value;
var system=document.getElementById("system").value;
var details=document.getElementById("description").value;
if(name.trim() == "")
{
alert("The name you entered is too short");
return false;
}
if(name.length > 64)
{
alert("The name you entered is too long");
return false;
}
if(system.trim() == ""
{
alert("System is not valid");
return false;
}
if(details == "")
{
alert("Description cannot be empty");
return false;
}
}
</script>
and I have the following form:
<form action="index.php" method="POST" onsubmit="return validate_entry();">
<table>
<tr>
<td><label for="submitted">Issue Submitted By</label></td>
<td><input type="text" name="submitted" id="submitted" tabindex="<?php echo $header[0]++; ?>"></td>
</tr>
<tr>
<?php $systems = get_system_names($connection);
if($systems==FALSE)
{
echo "<td></td>\n";
echo "<td></td>\n";
}
else
{
echo "<td><label for=\"system\">System Name</label></td>\n";
echo "<td><select name=\"system\" id=\"system\" tabinex=\"". $header[0]++. "\">\n";
echo "<option>Please Select</option>\n";
foreach($systems as $system)
{
echo "<option value=\"{$system[0]}\">{$system[1]}</option>\n";
}
echo "</select></td>\n";
}
?>
</tr>
<tr>
<td><label for="description">Issue Description</label></td>
<td><textarea name="description" id="description" tabindex="<?php echo $header[0]++; ?>"></textarea></td>
</tr>
<tr>
<td></td>
<td><input type="submit" name="submit" id="submit" tabindex="<?php echo $header[0]++; ?>"></td>
</tr>
</table>
<?php echo "</form>\n";
Make sure the positions of the JavaScript is after the html code
Try to test the JavaScript function using browser console
If it did work try to submit and handle other errors :)
I have a listbox that displays a couple of internships under following format
id - name :
1 - Computer Science
So far, I have create the function addRow in order to update my fields from form.
If I do
alert($montext)
I can display "1 - Computer Science", but I am looking only for the value "1".
I tried :
alert(<?php substr($montext,0,2)?>);
But seems that php inside "script" isn't being executed.
Because following code changes the value in the field:
document.getElementById('ti').value=$montext;
Because I'd like also to execute php code inside the script TAG.
I'm running under Apache.
If you could help me out. Thanks
Find hereby the used code.

You don't need to use PHP here. Use the javascript substring function - http://www.w3schools.com/jsref/jsref_substring.asp
For example
alert(montext.substring(0, 2));
Write your <script> on bellow your PHP and try this :
<script>
function addRow(title,text,description,id) {
var montext = $( "#idStage" ).text();
alert(montext);
document.getElementById('ti').value(montext);
/*document.getElementById('te').value=text;
document.getElementById('de').value=description;
document.getElementById('id').value=id;*/
}
function setText(title,text,description,id){
document.getElementById('title').value=title;
document.getElementById('text').value=text;
document.getElementById('description').value=description;
document.getElementById('id').value=id;
}
</script>
If you want to call variable from PHP, don't forget to use echo like this :
alert("<?php echo substr($montext,0,2); ?>");
