Load data from database according to the number I pressed
Hello, I have a form as you can see in the image below ...
... In what form do I load the first data from my database table ...
I want when I click on the number at the top of the list to load the relevant data.
My code is below (html form code not included) ...
<?php
$username = $_SESSION["username"];
if(isset($_POST['idWork'])){
$id = $_POST['idWork'];
$job_title = mysql_real_escape_string($_POST["job_title"]);
$company = mysql_real_escape_string($_POST["company"]);
$website = mysql_real_escape_string($_POST["website"]);
$start_date = mysql_real_escape_string($_POST["start_date"]);
$end_date = mysql_real_escape_string($_POST["end_date"]);
$start_year = mysql_real_escape_string($_POST["start_year"]);
$end_year = mysql_real_escape_string($_POST["end_year"]);
$work_history = mysql_real_escape_string($_POST["work_history"]);
if($start_year > $end_year)
{
echo '<script>ErrorMessage()</script>';
$id=$id-1;
$good = false;
}
else
{
$good = true;
}
if($good == true){
$query="UPDATE work
SET job_title = '$job_title', company = '$company', website = '$website', start_date='$start_date', end_date='$end_date', start_year='$start_year', end_year='$end_year', work_history='$work_history'
WHERE id='$id' AND username='$username'";
mysql_query($query)or die(mysql_error());
if(mysql_affected_rows()>=0){
echo "<p>Record Updated<p>";
echo "<script type='text/javascript'>;
window.location='addCV.php';
</script>";
}else{
echo "<p>Error Updating Record<p>";
echo "<script type='text/javascript'>;
window.location='addCV.php';
</script>";
}
}
}
else{
//first time, initialize as you wish. Probably need to get the first id for this user, using another query
$id = 0;
}
if($query = mysql_query("SELECT job_title,company,website,start_date,end_date,start_year,end_year,work_history FROM work WHERE id>'$id' AND username='$username' order by id asc limit 1") or die(mysql_error()))
{

Try this, the changes are explained in the comments:
<?php
$username = $_SESSION["username"];
if(isset($_POST['idWork'])){
$id = $_POST['idWork'];
$job_title = mysql_real_escape_string($_POST["job_title"]);
$company = mysql_real_escape_string($_POST["company"]);
$website = mysql_real_escape_string($_POST["website"]);
$start_date = mysql_real_escape_string($_POST["start_date"]);
$end_date = mysql_real_escape_string($_POST["end_date"]);
$start_year = mysql_real_escape_string($_POST["start_year"]);
$end_year = mysql_real_escape_string($_POST["end_year"]);
$work_history = mysql_real_escape_string($_POST["work_history"]);
if($start_year > $end_year)
{
echo '<script>ErrorMessage()</script>';
$id=$id-1;
$good = false;

You can do it with ajax request. JQuery provides us with a simple application interface.
There can be endless approaches, but for illustration purposes, here's how to do it.
- each binding element is a representative attribute, can be a class selector:
<a href="#" class="num" change_form_to="1"> 1 </a><a href="#" class="num" change_form_to="3"> 2 </a> ..etc
or you can do jQuery to decide what information to POST based on the element value. your preferences
-
see which number the user clicked
$('a').on('click',function(){var clicked = $(this).attr('change_form_to')})
so here the variable stores that special attribute value$(this).text()
or something like that to get a jQuery text literal -
then make a call to the php script
$.ajax({type:'POST',url:'dbh.php',data:{idWork:clicked},success: function(res){populate(res)}})
and when the success function is called, the answer came to call your custom made fill function
Everything to send:
$('a').on('click',function(){
var clicked = $(this).attr('change_form_to');
$.ajax({
type:'POST',
url:'dbh.php',
data:{idWork:clicked},
success: function(res){
console.log(res);
//populate(res); could look like this if your PHP dies with just outputing json_encode on some assoc array
var j = JSON.parse(res);
$('form input.name').value(j.name) ...etc
}
})
});
Your question says that you want to get data from the database, but in your sql syntax, you have your UPDATE logic
