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); ?>");

I have run an SQL statement to get all the records I need to show in a HTML table.
I have then run a while loop to display the records from the database. (The code for this is below.)
<table class="projects-table">
<tr>
<th>Complete?</th>
<th>Paid?</th>
<th>Project Name</th>
<th>£ / hr</th>
<th>End Date</th>
<th>Hours Logged</th>
<th><i class="fa fa-trash"></i></th>
</tr>
<?php
$select_id_jobs = mysqli_query($mysqli, "SELECT id FROM users WHERE username='$login_user'");
while($row = mysqli_fetch_array($select_id_jobs)) {
$id_jobs = $row['id'];
}
$select_jobs_with_usrid = mysqli_query($mysqli, "SELECT * FROM jobs WHERE username_id = '$id_jobs';");
while($row = mysqli_fetch_array($select_jobs_with_usrid)) {
?>
<tr id="<?php echo $rowId; ?>">
<td>
<!-- Complete Checkbox -->
<input type="checkbox" id="<?php echo $completeCheck;?>" onclick="compTask();">
</td>
<td>
<!-- Paid checkbox -->
<input type="checkbox" onclick="paidTask()">
</td>
<td>
<?php echo $row['project_title']; ?>
</td>
<td>
<?php echo $row['cost_hour']; ?>
</td>
<td>
<?php echo $row['completion_date']; ?>
</td>
<td>
<?php echo $row['time_spent']; ?>
</td>
<td>
<div class="delete-btn"><a onclick="deleteTask()">DELETE</a></div>
</td>
</tr>
<?php } ?>
</table>
As you can see from the checkbox for completing a task. What I want to do is use javascript so that when the checkbox is checked the text from the other records turns green.
I have included the javascript I am trying to use below. I don't know why but I can't access the inputs ID in order to change the css.
<script>
function compTask() {
if (document.getElementById("<?php echo 'complete-' . $row['id'] ?>").checked == true) {
document.getElementById("<?php echo 'tr' . $row['id']; ?>").style.color = "green";
alert("hello");
} else {
document.getElementById("<?php echo 'tr' . $row['id']; ?>").style.color = "black";
}
}
Okay easy way to do that is to print id as parameter in js function
something like that:
<input type="checkbox" id="<?php echo $completeCheck;?>"
onclick="compTask( '<?php echo $row['id'];?>' );">
and in js function deal with id from parameter:
function compTask(id) {
if (document.getElementById('complete-' + id).checked == true) {
document.getElementById('tr' + id).style.color = "green";
alert("hello");
}
}
Hy,
You need to add id in onclick="deleteTask('<?php echo $row['id']; ?>')">
Now in you function have id:
function deleteTask(id) { console.log(id) }
<?php session_start() ;
include 'databaseConnection.php' ;
$sqlCommand3 = "SELECT * FROM posts ;" ;
$result3 = mysqli_query($conn , $sqlCommand3);
$resultCheck = mysqli_num_rows($result3);
while ($row = mysqli_fetch_array($result3)) { ?>
<tr>
<td style="padding-left: 10px;">
<?php echo $row['poster']; ?>
</td>
<td style="padding-left: 45px;">
<?php echo $row['post_destination']; ?>
</td>
<td style="padding-left: 30px;">
<?php echo $row['post_readyTime']; ?>
</td>
<td style="padding-left: 45px;">
<?php echo $row['post_numberOfPassenger'];?>
</td>
<td style="padding-left: 32px;">
<?php echo $row['post_submitTime']; ?>
</td>
<td>
<form action="riderJoin.php" method="post">
<input type ="hidden" name ="id" value="<?php echo $row['post_id']; ?>" >
<input type =submit class="edit_btn" name = submit value = "Join">
</form>
</td>
<!--<td>
Delete
</td>-->
</tr>
<?php } ?>
</table>
</div>
</div>
<script type="text/javascript">
$("td:nth-child(4):contains('5')").addClass('redWord');
var x = document.getElementsByClassName('edit_btn');
<?php if (isset($_POST['submit'])) { ?>
var i = <?php echo $_SESSION['postId'] ; ?> - 1 ;
$(x[i]).val('Delete').css('background-color','red').css('color','white');
<?php }?>
</script>
How to add a new input (type = "submit" value="delete") with a new action (before the "join" button) whenever the $_POST['submit'] is set? I don't want to add a new input before each "join" button. Instead, I just want to add after a specific "join" button inside a cell when that specific "join" button is clicked. Also, if I click another 'join' button in other cell, a similar effect would happen too. So in the end, after clicking two "join" button, there should be only two delete button each added before the specific clicked "join" buttons. How to solve it ?
Thanks a lot :)

department table
dept_ID dept_name
1 Account
2 Finance
3 Marketing
Assume that my department table only have 3 records.
My requirement is the following:
- Click 1st delete button, show department ID = 1
- Click 2nd delete button, show department ID = 2
- Click 3rd delete button, show department ID = 3
However from my code, I can't meet my requirement. The department ID output that I get is 1 no matter what button I clicked.
Can someone help me?
No need to use a hidden input, you could just use the button tag instead:
<?php while($row = mysqli_fetch_array($result)) { ?>
<tr>
<td align="center"><?php echo $row['dept_ID']; ?></td>
<td align="center"><?php echo $row['dept_name']; ?></td>
<td>
<button type="submit" name="departmentID" class="buttonsPromptConfirmDeleteDepartment" value="<?php echo $row['dept_ID']; ?>">Delete</button>
</td>
</tr>
<?php } ?>
Of course, in the PHP script that does the form processing, access the POST index like you normally would:
$id = $_POST['departmentID'];
// some processes next to it
Note: Don't forget the <form> tag.
Additional Note: Don't forget to use prepared statements:
$sql = 'DELETE FROM department WHERE dept_ID = ?';
$stmt = $dbc->prepare($sql);
$stmt->bind_param('i', $id);
$stmt->execute();
// some idea, use error checking when necessary
// $dbc->error
Change
id="departmentID"
to
class="departmentID" and
Change
<script>
$(document).ready(function(){
$(".buttonsPromptConfirmDeleteDepartment").click(function(){
var departmentID = $('input#departmentID').val();
alert(departmentID);
});
});
to
<script>
$(document).ready(function(){
$(".buttonsPromptConfirmDeleteDepartment").click(function(){
var departmentID = $(this).next('input.departmentID').val();
alert(departmentID);
});
});
first of all dept_id in while loop and you are using same id for all dept..
another thing you can get dept_id upon button click using jquery.. like this
$('.buttonsPromptConfirmDeleteDepartment').click(function(){
dept_id = $(this).next('input').val();
})
I am trying to send each member email generate from the php if condition to an input text. The selection works well however, the problem I have is to find a way if multiple checkboxes are selected the emails sums spacing them with a coma.
Right now what I have is that if I check multiple checkboxes the last email selected replaces the old one.
Any Idea how Could I do this? Also if just one email is selected no coma have to be added and if the checkbox is unchecked the email is removed.
<?php if ( bp_has_members( "search_terms={$_POST['category']}")) : ?>

if ( select_check.is(':checked') ) {
// Do stuff
alert(select_email + " added");
$("#my_email_to_id").val(sum_email);
}else {
alert(select_email + " removed");

jQuery
$(document).ready(function ()
{

{
var buttonID = $(this).attr('id');
alert('table#' + buttonID);
$('table.hidden').hide();
$('table#' + buttonID).show();
});

The first code example describes how I generated a list of buttons, with the ID from the sql database. So every button has it's unique ID coming from the fitting database entry.
The second code example describes a table generated from database entries, every table gets a unique ID coming from the fitting database entry.
The third code example should get the ID of the button I click, get the table with the same ID as the button, hide all tables and only show the table with the same ID as the button.
The problem is, that it won't show anyting. It just hides all tables...
Just to let you know, I'm completly new to javascript/jQuery.
ID of an element must be unique(Now you have a table and button with the same id) so use a data-* attribute in the button to store the target element id.
<button type="button" data-target="<? echo $sub["InstrID"] ?>" class="submenu-button"><? echo $sub["InstrName"] ?></button>
then in the click handler
var buttonID = $(this).data('target');
