I have some code where I need to update a column of a table (MySQL) calling another php file without leaving the page where some tables might allow inline editing.
I have a point in the php echoing of the page, where an icon can be clicked to save input. The code at that point is:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<?php
$sql = "SELECT * FROM table WHERE a_column='certain_value'";
if (mysqli_query($conn, $sql)) {
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_assoc($result)) {
$note = $row["note"];
$code = $row["code"];
}
}
}
// some tabled elements not relevant for the issue
echo "<input type='text' id='note_1' name='note_1' value=$note readonly>";
echo "<input type='text' id='new_note' name='new_note'>";
echo "<img src='icon_to_click.png' id='icon_to_click' name='icon_to_click' >";
?>
<script type="text/javascript">
$(document).ready(function() {
$('#icon_to_click').click(function() {
var note_orig = document.getElementById('note_1').value;
var code_val = '<?php echo "$code" ?>';
var note_new = document.getElementById('new_note').value;
if (note_new != note_orig) {
$.ajax({
type: 'POST',
url: 'update_notes.php',
data: {'code': code_val, 'note': note_new},
success: function(response){
document.getElementById('note_1').value = note_new;
}
});
}
});
});
The relevant code of update_notes.php is:
<?php
// connection
$unsafe_note = $_POST["note"];
$code = $_POST["code"];
require "safetize.php"; // the user input is made safe
$note = $safetized_note; // get the output of safetize.php
$sqlupdate = "UPDATE table SET note='$note' WHERE code='$code'";
if (mysqli_query($conn, $sqlupdate)) {
echo "Note updated";
} else {
echo "Problem in updating";
}
// close connection
?>
Now when I run the code and look at the tool, it gives me the error: Uncaught ReferenceError: $ is not defined, linking the error to this line of the previous js code:
$(document).ready(function() {
So, how can I fix that?
It means that you tried to use Jquery in your Javascript Code without calling Jquery Library or the code is called without the library was fully loaded.
I notice :
That you haven't closed your script tag
You use Jquery so you can use $('#id_name') to select element by Id instead of document.getElementById('note_1')
Get element value by using Element.val() instead of Element.value
Try to edit your code like this
<?php
$sql = "SELECT * FROM table WHERE a_column='certain_value'";
if (mysqli_query($conn, $sql)) {
$result = mysqli_query($conn, $sql);
if (mysqli_num_rows($result) > 0) {
while($row = mysqli_fetch_assoc($result)) {
$note = $row["note"];
$code = $row["code"];
}
}
}
?>

Hey I have faced same error a day before,this is because you have missed using a jquery library script that is needed. please try using some Updated Jquery CDN . :) It will definitely help
OR
include the jquery.js file before any jquery plugin files.
I have a button called rename that when pushed, executes in jQuery a rename.php file. Inside that php file the program selects data from a mysql, creates an array with that data, and processes an array in to json_encode($array);. How can I then get that json encoded array and echo it out into javascript?
I'm trying to echo the array out so that javascript displays my images src's.
This is my second line of ajax so I just wrote the javascript out as if it were php because I'm not sure of the commands or structure in js.
$.ajax
(
{
url:"test4.php",
type: "GET",
data: $('form').serialize(),
success:function(result)
{
/*alert(result);*/
document.getElementById("images_to_rename").innerHTML = foreach(jArray as array_values)
{
"<img src=\""array_values['original_path']"/"array_values['media']"/>";
}
}
}
);
and my jQuery php file:
<?php
include 'db/mysqli_connect.php';
$username = "slick";
if(empty($_GET['image_name']))
{
echo '<div class="refto" id="refto">image_name is empty</div>';
}
else
{
echo '<div class="refto" id="refto">image_name is not empty</div>';
foreach($_GET['image_name'] as $rowid_rename)
{
//echo '<br><p class="colourful">rowid_refto: '.$rowid_refto.'</p><br>';
$active = 1;
$command = "Rename";
$stmt = $mysqli->prepare("UPDATE ".$username." SET active=?, command=? WHERE rowid=?");
$stmt->bind_param("isi", $active, $command, $rowid_rename);
$stmt->execute();
$stmt->close();
}
//go to database, get parameters of sort
$command = "Rename";
$active = 1;
$stmt = $mysqli->prepare("SELECT original_path, media FROM " . $username . " WHERE active=? and command=?");
$stmt->bind_param("is", $active, $command);
$stmt->execute();
$result = $stmt->get_result();
while($row = $result->fetch_assoc())
{
$arri[] = $row;
}
foreach($arri as $rows) //put them into workable variables
{
$rowt = $rows['original_path'];
$rowy = $rows['media'];
//echo 'rows[\'original_path\'] = '.$rows['original_path'].''.$rows['media'].'';
}
$stmt->close();
echo json_encode($arri);
?>
<script type="text/javascript">
var jArray= <?php echo json_encode($arri); ?>;
</script>
<?php
}
echo "something2";
?>
My PHP file is a jQuery url:"test4.php", type: "GET", and is not the main file. The main file is called main.php and the test4.php is something that's called in jQuery when the user clicks on rename.
Somebody suggested console log so here's what chrome says:
<div class="refto" id="refto">image_name is not empty</div>[{"original_path":"Downloads","media":"shorter.jpg"},{"original_path":"Album 2","media":"balls.jpg"}] <script type="text/javascript">
var jArray= [{"original_path":"Downloads","media":"shorter.jpg"},{"original_path":"Album 2","media":"balls.jpg"}];
</script>
something2
Your ajax php file isn't render in browser, then the variable jArray is undefined. With your case, let return php file to json and you can get it as variable in result.
<?php
include 'db/mysqli_connect.php';
$username = "slick";
if (empty($_GET['image_name'])) {
//echo '<div class="refto" id="refto">image_name is empty</div>';
} else {
//echo '<div class="refto" id="refto">image_name is not empty</div>';
foreach ($_GET['image_name'] as $rowid_rename) {
//echo '<br><p class="colourful">rowid_refto: '.$rowid_refto.'</p><br>';
$active = 1;
$command = "Rename";
$stmt = $mysqli->prepare("UPDATE " . $username . " SET active=?, command=? WHERE rowid=?");
$stmt->bind_param("isi", $active, $command, $rowid_rename);
$stmt->execute();
$stmt->close();
}
//go to database, get parameters of sort
$command = "Rename";
$active = 1;
$stmt = $mysqli->prepare("SELECT original_path, media FROM " . $username . " WHERE active=? and command=?");
$stmt->bind_param("is", $active, $command);
$stmt->execute();
$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
$arri[] = $row;
}
foreach ($arri as $rows) { //put them into workable variables
$rowt = $rows['original_path'];
$rowy = $rows['media'];
//echo 'rows[\'original_path\'] = '.$rows['original_path'].''.$rows['media'].'';
}
$stmt->close();
echo json_encode($arri);
//stop render here
die();
}
?>
php file need return only json string. Then we'll get result as json variable in javascript.
And Js:
$.ajax
(
{
url:"test4.php",
type: "GET",
data: $('form').serialize(),
success:function(result)
{
var jArray = JSON.parse(result);
/*alert(result);*/
var txt = "";
jArray.forEach(function(array_values){
txt += `<img src=\""array_values.original_path."/"array_values.media"/>`;
})
document.getElementById("images_to_rename").innerHTML = txt;
}
}
);

Alright. I was still missing the following code from you, so you'll have to add these yourself:
The HTML element with parameter id="id" needed for $('#id').val(text.id);
The HTML element with parameter id="url1" needed for $('#url1').val(text.url);
The PHP response code for JS function showdata(); inside feeds.php
Since I don't have your database here, I was unable to test the code. It should work fine, but if anything is wrong, just let me know:
PHP file: index.php

include_once("pdo.class.php");

I would normally have two scripts (.php) files.
One to display the form and one to catch the submission (possibly via ajax)
You can have both in the same .php file but then you'd want to check before outputting any text whether you have any POST data to process.
If you go with two files
view file:
<html>
<body>
<form method="POST" action="path/to/formname_submit.php">
your form fields go here
<input name="somefield"/>
...
</form>
<script>
//your jquery code
....
</script>
<body>
</html>
submit file
<?php
if (empty($_POST['id'])){
die("no ID");
};
if (empty($_POST['editvalue'])){
die("no editvalue");
}
//get a database connection
$db = mysqli(DBHOST,DBUSER,DBPASS,DBNAME);
$db->set_charset("utf8");
// read in the POST data
//should do some more validation / anti SQL injection
$editvalue = $db->escape_string($_POST['editvalue']);
$id = intval($_POST['id']);
$sql = "UPDATE sometable SET `field` = '$editvalue' WHERE id=$id";
if ($db->query($sql)){
echo 'Success';
}
else {
echo 'UPDATE ERROR:'.$db->errno.': '.$db->error;
}
your jquery can now send the data to the second script and see if the data coming back from the call is 'Success' and display an error if it's not.

Im trying to get my PHP script called from AJAX (that is in my main php file).
Here's an example of what it is supposed to do: http://jsfiddle.net/xfuddzen/
The HTML source code shows only desk_box DIV being created (which is in my main.php). station_info DIV (being created in the display_station.php) is not there. How can I fix this? thanks in advance
Problem: DIVs from my display_stationinfo.php are not being created by using the AJAX call.
main.php with JQuery/AJAX part:
<div id="map_size" align="center">
<?php
//didsplay Desk stations in the map
while($row = mysqli_fetch_assoc($desk_coord_result)){
//naming X,Y values
$id = $row['coordinate_id'];
$x_pos = $row['x_coord'];
$y_pos = $row['y_coord'];
//draw a box with a DIV at its X,Y coord
echo "<div class='desk_box' data='".$id."' style='position:absolute;left:".$x_pos."px;top:".$y_pos."px;'>id:".$id."</div>";
} //end while loop for desk_coord_result
?>
<script type="text/javascript">
//Display station information in a hidden DIV that is toggled
//And call the php script that queries and returns the results LIVE
$(document).ready(function() {
$('.desk_box').each((function(){(this).click(function() {
var id = $(this).attr("data")
$("#station_info_"+id).toggle();
$.ajax({
url: 'station_info.php',
data: { 'id': id },
type: 'POST',
dataType: 'json',
success: function(json) {
$("#station_info_"+id).css({'left':json.x_pos ,'top': json.y_pos}).append('<p>Hello the id is:'+ json.id +'</br>Section:'+ json.sec_name +'</p>');
}//end success
});//end ajax
});//end click
});//end ready
</script>
</div> <!-- end map_size -->
display_station.php (script that I want to call):
<?php
include 'db_conn.php';
//query to show workstation/desks information from DB for the DESKS
$station_sql = "SELECT coordinate_id, x_coord, y_coord, section_name FROM coordinates";
$station_result = mysqli_query($conn,$station_sql);
//see if query is good
if ($station_result === false) {
die(mysqli_error());
}
//Display workstations information in a hidden DIV that is toggled
$html = '';
if($station_result->num_rows > 0){
while($row = $station_result->fetch_object()) {
$id = $row->coordinate_id;
$html .= "<div class='station_info_' id='station_info_$id' style='position:absolute;left:{$row->x_coord}px;top:{$row->y_coord}px;'>Hello the id is:$id</br>Section:{$row->section_name}</br></div>";
}
}
else{
// no results - may want to do something with $html
$html = "no result given";
}
$station_result->free();
$conn->close();
echo $html;
?>
Why dont you filter the coordinate in the query? Like this:
$station_sql = "SELECT coordinate_id, x_coord, y_coord, section_name FROM coordinates WHERE coordinate_id = " . $_GET['coordinate_id'];
And in jquery code:
url: 'display_stationinfo.php?coordinate_id=' + id,
Let's start with your database connection, which should be on a separate secure page.
connect.php:
<?php
function db(){
return new mysqli('host', 'username', 'password', 'database');
}
?>
Obviously, your host will not be 'host'.
Now main.php:
<?php
// only use for PHP on this page for initial page load - target other pages with AJAX
?>
<!DOCTYPE html>
<html xmlns='http://www.w3.org/1999/xhtml' xml:lang='en' lang='en'>

<meta http-equiv='content-type' content='text/html;charset=utf-8' />
<title>This is Where Your Title Goes</title>

</head>
<body>
<div id='map_container'>
<div id='map_size'>
</div>
</div>
</body>
</html>
Now for main.js:
//<![CDATA[
$(function(){
var ms = $('#map_size');
$.post('main_init.php', {init:'1'}, function(d){
for(var i in d){
var di = d[i], x = di.x, y = di.y;
var sti = $("<div class='station_info_' id='station_info_"+i+"'></div>").css({
left:x,
top:y
});
// HTML id, class, and name attributes cannot start with a number
$("<div class='desk_box' data='"+i+"'>id:"+i+'</div>').css({
left:x,
top:y
}).appendTo(ms).append(sti).click(function(){
var info = $(this).next();
$.post('live_info.php', {station_id:info.attr('id').replace(/^station_info_/, '')}, function(r){
// do stuff with r
info.html('love:'+r.love+'<br />hate:'+r.hate).toggle();
}, 'json');
});
}
}, 'json');
});
// use CSS to do `.desk_box,.station_info_{position:absolute;}`
//]]>
Now for main_init.php:
<?php
if(isset($_POST['init']) && $_POST['init'] === '1'){
include_once 'connect.php'; $db = db(); $json = array();
$q = $db->query("SELECT * FROM table WHERE"); // example only
if($q->num_rows > 0){
while($r = $q->fetch_object()){
$json[strval($r->coordinate_id)] = array('x' => $r->x_coord, 'y' => $r->y_coord);
}
}
else{
// no results
}
$q->free(); $db->close();
echo json_encode($json);
}
else{
// could be a hack
}
?>
Here's what live_info.php might look like:
<?php
if(isset($_POST['station_id'])){
include_once 'connect.php'; $db = db(); $json = array();
// example only - you will only get one `$row` if query is done specific, so while loop is not needed
$q = $db->query("SELECT love,hate FROM some_table WHERE id='{$_POST['station_id']}'");
if($q->num_rows > 0){
$row = $q->fetch_object();
// it's okay to overwrite array in this case
$json = array('love' => $row->love, 'hate' => $row->hate);
}
else{
// no results
}
$q->free(); $db->close();
echo json_encode($json);
}
else{
// may be a hack
}
?>
