Here, If I write name of textbox is id from an array, then how it would be use in session.?
Updated:
My code is:
foreach($abc as $row)
{
<input type="text" name="<?php echo $row['id']; ?>" class="txt" id=txt_"<?php echo $row['id']; ?>" onblur="doAjax(this)"/>
}
Javascript code:
$(document).on('blur','.txt',function(){
$.ajax({
type: "GET",
url: "view_orders_checked_array.php",
data: {task: 'alltxt'},
async: false
});
});
In view_orders_checked_array.php:
if($task == "alltxt")
{
$_SESSION["textareaID"] = [];
foreach($rows as $row)
{
$al[] = array_push($_SESSION["textareaIDs"], $row["id"]);
}
print_r($al);
}
So, how it would possible to store textbox value in session array.?
Start the session at the top of every page that you want to access the session:
<?php session_start();
Then to add data to the session array:
<?php $_SESSION["foo"] = $bar; ?>
So if your textarea ID is $row["id"], you can do:
<?php $_SESSION["textareaID"] = $row["id"]; ?>
then call it whenever you want by doing:
<?php echo $_SESSION["textareaID"]; ?>
Of course, you can name the session array variable anything you want.
Or in a foreach loop:
<?php
$_SESSION["textareaIDs"] = [];
foreach($rows as $row){
array_push($_SESSION["textareaIDs"], $row["id"]);
} ?>

I am trying to pass div id to javascript and print it out on console as :
<?php echo 67;?>
The 67 is id here. I was wondering how can I store this value in my javascript variable storeid as var storeid = 67?
My code:
echo "<h2 class='editme' id='<?php echo $id;?>' contentEditable='true'> Hello</h2>";
echo "<script>
$('h2.editme').click(function(){
console.log(this.id);
var storeid;
});
</script>";
Also, I want to use that id value to update the values in my sql. I can only test my code once I could somehow get the value of that id. How can I store the value of the id to javascript variable?
My code (This is to update sql once I get the id) - Not sure if it's right I can test it after getting id value:
echo "<h2 class='editme' id='<?php echo $id;?>' contentEditable='true'> Hello</h2>";
echo "<script>
$('h2.editme').click(function(){
var content2 = $(this).html();
console.log(this.id);
var storeid;//once I get the id
$.ajax({
url: 'updateDescription(storeid, content2)',
success: function(respon) {
$('.editme').html(respon);
}
});
});
</script>";
function updateDescription($user_unique_id, $content2)
{
try {
require "testing.php";
$sql = "UPDATE icecream SET
desc = :desc
WHERE id = :id";
$stmt->bindParam(':desc', $content2, PDO::PARAM_STR);
$stmt->bindParam(':id', $user_unique_id);
$stmt->execute();
echo 'Record updated';
} catch (PDOException $e) {
echo 'Connection failed ' . $e->getMessage();
}
}
this way:
echo '<script>
var storeid = '. $id .'
</script>';
more readable way:
// somefile.php
<?php
$id = 67;
?>
<h2 class='editme' id='<?php echo $id;?>' contentEditable='true'> Hello</h2>
<script>
var storeid = <?php echo $id; ?>
// rest of javascript code
</script>
<?php
// rest of the php code
i am working on a project and come across a module.
page1
user have to search from search bar which will take him to page 2.
page2
On page 2 all fetched results will get displayed to user in div's. Each result has a checkbox associated with it.
when i click on add to compare check box ,ajax call is executed and fetched selected result should appear in hidden div.
my problem is it is only shows first result in hidden div and not working with another result.
My code of page 2
<script type="text/javascript">
$(document).ready(function()
{
var check = $('#compare').val();
$("#compare").change(function() {
if(this.checked) {
$.ajax({
type: 'POST',
url: 'compare.php',
dataType : 'JSON',
data:{value : check},
success: function(data)
{
console.log(data);
$('#compare_box').html(data);
}
});
$("#compare_box").show();
}
else
{
$("#compare_box").hide();
}
});
});
</script>
</head>
<body>
<?php
$query = $_GET['search_bar'];
$query = "call fetch_data('$query')"or die(mysqli_error($conn));
$result = mysqli_query($conn,$query);
while($row = mysqli_fetch_array($result))
{
$id = $row['course_id'];
$title = $row['course_title'];
$description = $row['course_description'];
$course_url = $row['course_url'];
$video_url = $row['course_video_url'];
$fee = $row['course_fee'];
$duration = $row['course_duration'];
$start_date = $row['course_start_date'];
$university = $row['university_name'];
$course_provider = $row['course_provider_name'];
$instructor = $row['instructor_name'];
$_SESSION['result'][$id] = Array('id'=> $id,'course_title' => $title,'course_description'=> $description,'course_url' => $course_url,'video_url' => $video_url,'fee' => $fee,'course_duration'=>$duration,'start_date'=>$start_date,'university' => $university,'course_provider'=>$course_provider,'instructor'=>$instructor);
?>
<div id='compare_box'>
</div>
<div class="col-md-3 photo-grid " style="float:left">
<div class="well well-sm">
<a href="final.php?id=<?php echo $id;?>&name=<?php echo $title;?>" target="_blank">
<h4><small><?php echo $title; ?></small></h4>
</a>
<br>
<input type ='checkbox' name="compare" id="compare" value="<?php echo $id;?>">add to compare
</div>
</div>
<?php
}
?>
page3 compare.php
<?php
session_start();
include 'includes/dbconfig.php';
$check = $_POST['value'];
$sql = "SELECT * from course_info_table where course_id = '$check' " or die(mysqli_error($conn));
$result = mysqli_query($conn,$sql);
$index = 0;
while($row = mysqli_fetch_array($result))
{
$title = $row['course_title'];
?>
<?php
}
echo json_encode($title);
?>
You can change
<input type ='checkbox' name="compare" id="compare" value="<?php echo $id;?>">
to
<input type ='checkbox' name="compare" class="compare" value="<?php echo $id;?>">
^you can only have one unique 'id' value in your html doc, which means your first id="compare" will work fine and others with id="compare" will be ignored by the DOM tree

I have this index.php file to show some stuff in tables from loop:
$sql = 'SELECT id FROM usertbl';
$stmt = $hund->runQuery($sql);
$stmt->execute();
$row = $stmt->fetchALL(PDO::FETCH_ASSOC);
<?php foreach ($row as $runloop) { ?>
<table><th> <?php echo $runloop['id']; ?> </th></table>
<?php } ?>
However, I wish to have auto refresh for those tables. So I have this new file data.php and a updated index.php:
data.php:
$sql = 'SELECT id FROM usertbl';
$stmt = $hund->runQuery($sql);
$stmt->execute();
$row = $stmt->fetchALL(PDO::FETCH_ASSOC);
print_r($row);
index.php:
<div id="show"></div>
<script type="text/javascript">
$(document).ready(function() {
setInterval(function () {
$('#show').load('data.php')
}, 3000);
});
</script>
<?php foreach ($row as $runloop) { ?>
<table><th> <?php echo $runloop['id']; </th></table>
<?php } ?>
This will refresh and print the output in the above <div>:
<div class="show"></div>
And it works great, but I don't really have any clue how to put that inside the loop for the tables, just as the first index.php file. Any suggestions of a direction to take in this matter?
You can use ajax to call data.php and return the response in json format for a better approach
Try:
js
function populate(){
var items= [];
$.ajax({
url: 'data.php',
type: 'GET',
dataType: 'json',
success: function(data){
//do something with data here
console.log(data);
//loop through data and push to array
$.each(data, function(i,v){
items.push('< th >'+v+'< /th >');
});
//join array and append to table
$('#sampleTable tbody').html(items.join(','));
},
error: function(err){
console.log(err.responseText);
}
});
}
//call populate every 10 secs (example only , you can change to how many seconds you like)
setTimeout(function(){
populate();
},10000);
data.php
$sql = 'SELECT id FROM usertbl';
$stmt = $hund->runQuery($sql);
$stmt->execute();
$row = $stmt->fetchALL(PDO::FETCH_ASSOC);
echo json_encode($row);
In this line you forgot to close <?php ...
Possibly that's why foreach loop doesn't work correctly
<?php foreach ($row as $runloop) { ?>
<table><th> <?php echo $runloop['id']; ?></th></table>
<?php } ?>
Put these lines in data.php where print_r() is.
It seems like when i echo out the result in php, it will loop through the database and display it in the "echo" below but if I try to display it using javascript, it does not even loop. what's the problem in the javascript?
<?php
while($row = $result->fetch()){
$id = $row['id'];
echo $id; //loops through and displays the all the id's in order in the database
?>
//this only displays the first id and doesn't loop even though it is in the php while loop
<script>
document.getElementById("test").innerHTML = "<?= $id ?>";
</script>
<span id="test"></span>
<?php
}
?>
please try with this
<?php
while($row = $result->fetch()){
$id = $row['id'];
echo $id; //loops through and displays the all the id's in order in the database
?>
//this only displays the first id and doesn't loop even though it is in the php while loop
<!-- change in id name -->
<span id="test_<?=$id?>"></span>
<script type="text/javascript">
//change here
document.getElementById("test_<?=$id?>").innerHTML = "<?= $id ?>";
</script>
<?php
}
?>
As I wrote in the title I have this part of code in page page.php that is in a subfolder admin. So the path of page is ../admin/page.php:
<select name="my_select" id="my_select" onchange="function(this.value);">
<?php
include "../db/db_config.php";
$conn = mysql_connect($host,$user,$password)or die(mysql_error());
mysql_select_db($db, $conn);
$query="Query";
$res=mysql_query($query,$conn);
while($row=mysql_fetch_array($res)){
$id=$row['id'];
$text=$row['text'];
echo "<option value='$id'>$text</option>";
}
}
?>
</select>
$var = $_POST['my_select'];
echo "I have selected $var";
I use a function that I have found on internet:
function fetch_select(val)
{
$.ajax({
type: 'post',
url: 'page.php',
data: {
get_option:val
},
success: function (response) {
document.getElementById("my_select").innerHTML=response;
}
});
}
What I have to do to take value in $var? Because I need this value to build other things. Is it possible?
EDIT:
Probably I don't explain very well my problem. I don't have very good with ajax because I never use it. I have a deadline so I can't study it now.
Now I have this situation:
I have a select-form with an input submit. After click on the button I use $_POST['myoption'] and I get the value.
Then I do it:
if($var == 1)
//a query from database
else if($var == 2)
//another different query
else
//other but no query
This work correctely. I need to change it and use in the same page. How can I do the same?
You don't to do a POST to do this you can do it with jQuery.
<?php
include "../db/db_config.php";
$conn = mysql_connect($host,$user,$password)or die(mysql_error());
mysql_select_db($db, $conn);
$query="Query";
$res=mysql_query($query,$conn);
?>
<select name="my_select" id="my_select">
<?php
while($row=mysql_fetch_array($res)){
$id=$row['id'];
$text=$row['text'];
echo "<option value='$id'>$text</option>";
}
?>
</select>
<span id="selected"></span>
<script>
$("#my_select").change(function() {
$("#selected").html($("#my_select option:selected").text());
});
</script>
This will give the select value to PHP:
<?php
include "../db/db_config.php";
$conn = mysql_connect($host,$user,$password)or die(mysql_error());
mysql_select_db($db, $conn);
$query="Query";
$res=mysql_query($query,$conn);
if (isset($_POST['my_select'])) {
$var = $_POST['my_select'];
} else {
$var = '';
}
?>
<form id="my_form" action="" method="POST">
<select name="my_select" id="my_select">
<?php
while($row=mysql_fetch_array($res)){
$id=$row['id'];
$text=$row['text'];
echo "<option value='$id'>$text</option>";
}
?>
</select>
</form>
<span id="selected">I have selected <?php echo $var; ?></span>
<script>
$("#my_select").change(function() {
$('#my_form').submit();
});
</script>
