PHP - Please Look At This Code And See What I Am Doing Wrong. It's About Adding And Displaying A Record Using Php , Mysql And Ajax.
All I am trying to do is add a record on a page without the page refreshing. For that ajax is used. Here is the code.
It does not add the record to mysql table. Can anyone tell me what I am doing wrong?
record.php
<!DOCTYPE HTML>
<html lang="en">
<head>
<script type="text/javascript" src="js/jquery-1.11.0.min.js"></script>
<script type="text/javascript" >
$(function() {
$(".submit_button").click(function() {
var textcontent = $("#content").val();
var name = $("#name").val();
var dataString = 'content='+ textcontent + '&name='+name;
if(textcontent=='')
{
alert("Enter some text..");
$("#content").focus();
}
else
{
$("#flash").show();
$("#flash").fadeIn(400).html('<span class="load">Loading..</span>');
$.ajax({
type: "POST",
url: "action.php",
data: dataString,
cache: true,
success: function(html){
$("#show").after(html);
document.getElementById('content').value='';
$("#flash").hide();
$("#content").focus();
}
});
}
return false;
});
});
</script>
</head>
<body>
<?php
$record_id = $_GET['id']; // getting ID of current page record
?>
<form action="" method="post" enctype="multipart/form-data">
<div class="field">
<label for="title">Name *</label>
<input type="text" name="name" id="name" value="" maxlength="20" placeholder="Your name">
</div>
<div class="field">
<label for="content">content *</label>
<textarea id="content" name="content" maxlength="500" placeholder="Details..."></textarea>
</div>
<input type="submit" name="submit" value="submit" class="submit_button">
</form>
<div id="flash"></div>
<div id="show"></div>
</body>
</html>
action.php
if(isset($_POST['submit'])) {
if(empty($_POST['name']) || empty($_POST['content'])) {
$error = 'Please fill in the required fields!';
} else {
try {
$name = trim($_POST['name']);
$content = trim($_POST['content']);
$stmt = $db->prepare("INSERT INTO records(record_id, name, content)
VALUES(:recordid, :name, :content");
$stmt->execute(array(
'recordid' => $record_id,
'name' => $name,
'content' => $content
));
if(!$stmt){
$error = 'Please fill in the required fields.';
} else {
$success = 'Your post has been submitted.';
}
} catch(Exception $e) {
die($e->getMessage());
}
}
}
Similar TutorialsHello everyone, I begin in everything web related but I have been programming for years. I tried to code something simple : small Mysql DB (works fine) and to begin a search bar to browse data. I adapted a code that I understood provided here : https://www.cloudways.com/blog/live-search-php-mysql-ajax/. Base principle is simple : as you type in your query, it will pass the text to script.js that will forward this request to ajax.php file. In the ajax.php, a javascript function named “fill()” will pass the fetched results. This function will also display the result(s) into “display” div in the “search.php” file. The problem is that when I type anything it displays, below the search bar, at the moment I type a character: Quote
'; //Fetching result from database. while ($Result = MySQLi_fetch_array($ExecQuery)) { ?> ")'>
instead of the actual answer from my database (no error in the browser console). I tested the SQL query + the user I provide and everything seems fine. Any clue what could be the root cause ? I strongly suspect a mistake in the code as I already corrected one (script.js instead of scripts.js) but I really cannot figure out where. Thanks in advance,
problematic code (ajax.php):
<?php
//Including Database configuration file.
include "db.php";
//Getting value of "search" variable from "script.js".
if (isset($_POST['search'])) {
//Search box value assigning to $Name variable.
$Name = $_POST['search'];
//Search query.
$Query = "SELECT Name FROM search WHERE Name LIKE '%$Name%' LIMIT 5";
//Query execution
$ExecQuery = MySQLi_query($con, $Query);
//Creating unordered list to display result.
echo '
<ul>
';
//Fetching result from database.
while ($Result = MySQLi_fetch_array($ExecQuery)) {
?>
<!-- Creating unordered list items.
Calling javascript function named as "fill" found in "script.js" file.
By passing fetched result as parameter. -->
<li onclick='fill("<?php echo $Result['Name']; ?>")'>
<a>
<!-- Assigning searched result in "Search box" in "search.php" file. -->
<?php echo $Result['Name']; ?>
</li></a>
<!-- Below php code is just for closing parenthesis. Don't be confused. -->
<?php
}}
?>
</ul>

It adds and deletes but it does it by passing the date directly to the PHP files and refreshing the screen. I want it to do it through the jquery Ajax script.

This should work according to what I have read but no mater what I try the jquery script does not work. Some help getting me In the right direction would be great. Code: Hello, is there something like this? If mysql record is admin, then a block of code How do I do something like that Right now I redirect to index page after I delete a record. However I am looking to make it so that I can delete a record without redirecting the page. I know this can be accomplised using Ajax. I have spent countless hours before trying to make it work, but it did not work.
So here is a basic setup I created. Can you please update it with ajax code so that I can see how it's done properly?

Hey guys, Having a slight problem with part of the code in my index.php file Code: [Select] mysql_select_db('db_name', $con); $result = mysql_query("SELECT * FROM spy ORDER BY id desc limit 25"); $resulto = mysql_query("SELECT * FROM spy ORDER BY id desc"); $count = mysql_num_rows($resulto); while($row = mysql_fetch_array($result)) { ?> <div class="contentDiv">Someone is looking at <?=$row[title];?> Stats for "<a href="/<?=$row[type];?>/<?=$row[code];?>/<?=$row[city];?>"><?=$row[code];?> <?=$row[city];?></a>"</div> <?}?> </div> <div id="login"></div> <? include("footer.php"); ?> </div> </body> </html> I'm getting the following error when viewing the file Code: [Select] Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in ~path to file/index.php on line 70 Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in ~path to file/index.php on line 71 where lines 70 and 71 are $count = mysql_num_rows($resulto); while($row = mysql_fetch_array($result)) Any ideas on how to fix this? Hi. I currently have php java to get my database results and limit the amount of data shown by a given value. The js includes buttons to go forward or backward in the database. Everything is all fine and dandy except I'm trying to add a very simple search for the user as well. I want the user to be able to select either "firstname" or "lastname" to search through the database and display the resulting rows based of the first three characters entered into the search criteria. I'm not sure where to start on this... Do I have to add something the js (I'm not very familiar with js), or should I add mysql_query's in the php linked file?

The code is intended to update a record, but if it does not exist, then create it. This snippet always creates a new record, and will not update an existing one.

I have a textarea that is entered into a database. When this is edited, I want to store and display a list of all the changes that have been made to it. Like a conversation in a forum. The reason for this is that I want past changes to be locked from editing. Would a new database table storing only this text fields data need to be created? Maybe have column for the work request number and a second column for the text entered? But then wouldn't I need an third identifier column so the changes can be displayed in the right order?

Because I have checked my code and I have no idea where I am going wrong I have the following code: Code: [Select] $result = mysql_query("SELECT * FROM ESSAY_QUESTIONS WHERE SUBJECT = 'ENGLISH'") or die(mysql_error()); while($essay_data=mysql_fetch_array($result)){ $question = $essay_data['QUESTION']; $id = $essay_data['ID']; echo "<a href=\"englishessays.php?id=$id>"; echo "$question </a>"; echo "<br><br>"; } It seems to be almost working but it just displays one link and the address is all the rest of the code including </a>"; echo "<br><br>"; and other questions. I presume there's an error with how I've written the echo statements so can anyone see it? Or can anyone suggest a better way to do this? On the next page, the php will read the ID from the address and display the information form that record. Hi I've been scouring the net and I cant find anything that works. Can someone tell me how to put a delete button next to each record? Any help is appreciated, thank you! Code: [Select] $term = strtolower ($_POST['term']); $sql = mysql_query("select * from $table where first like '%$term%' or last like '%$term%'"); while ($row = mysql_fetch_array($sql)){ echo 'ID: '.$row['id']; echo '<br/> first: '.$row['first']; echo '<br/> last: '.$row['last']; echo '<br/> phone: '.$row['phone']; echo '<br/> mobile: '.$row['mobile']; echo '<br/> fax: '.$row['fax']; echo '<br/> email: '.$row['email']; echo '<br/> web: '.$row['web']; echo '<br/><br/>'; } ?> </p> I making an web app for teachers to assess their students online. The problems I am currently having are on select only one record is displayed and after update no records are displayed in the form even though it was successfully updated.. The program has two files, index.php and process.php. The problems started when got the class name into the query to search and display the class. $result = $mysqli->query("SELECT * FROM data WHERE classroom = '".$classroom."' ORDER BY '.name';") or die($mysqli->error); The query works but doesn't order by name I would like. I would be grateful if anyone could cast an eye over it and give me some tips. Thanks guys. The beers are on me if anyone can sort it, but you'll have to come to Phnom Penh, Cambodia as that is where I live. Anyway here's the code. process.php
<html>
<?php
session_start();
$mysqli = new mysqli("localhost","ray","password","reports") or die(mysqli_error($mysqli));
$id = 0;
$update = false;

$id = $_GET['edit'];
$update = true;
$result = $mysqli->query("SELECT * FROM data WHERE id=$id") or die($mysqli->error());
if(isset($result->num_rows) && $result->num_rows > 0) {
$row = $result->fetch_array();
$name = $row['name'];
$classroom = $row['classroom'];
$pacomment = $row['pacomment'];
}
}
if (isset($_POST['update'])){

Edited July 25, 2020 by raymon What is the best way to display the next record on a web page, from a list of records, without executing the query over and over again each time you display the next record? For example, imagine my user has a list of messages displayed on a web page, and the user filters that list to display all messages with the title "Test", and let's say that returns 12 records. He then clicks on record 1 to read that message. Once he is done reading it, he then wants to read msg 2, and then msg 3 etc. He could hit the Back button in his browser and click on the next record from the list, but it would be more useful to just click on a link that says "Next" which displays the next message in the filtered list of messages (without having to go back to the list). A lot of web sites do this sort of thing, but what is the best way to do it? Do you have to run the original query again each time a new message is loaded, so you know which message is next, or can you somehow store the query to save the server from having to run the same query over and over again? If a user is viewing a list of pictures for example, they could be flicking through the pictures quite quickly, and I would not like to have the server running the same query over and over again every few seconds when it doesn't need to. Advice? (Thanks.) Here is my add driver button This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=347192.0 Hello, I had this code that checks for a form validity using AJAX: ereg("^[a-zA-Z0-9]+$ This will check only for a-z,0-9 and A-Z, how can I allow white spaces to be inserted? Thanks Could someone please tell me why this displays 3 columns correct and then all moves over.
