Can someone help me on pagination syntax for php webpage. I have a set a pagination code to display 20 records per page. The records are displaying based on 'start date' and 'end date'.
The issue is, it works on page 1 but when I click on page 2 in pagination then it won't work. I assume the values of $_POST['startdate'] and $_POST['enddate] are not forwarding on page2.

$_POST superglobal variable is populated by PHP when a POST HTTP request is processed. This is the case on the request for page 1.
However, your go2page() function is mutating location.href, which generates a GET HTTP request, and so does pagination links.
You should append your startdate and enddate params to the pagination URLs, to forward your params to the next/previous requests :
qm.php?page=<YOUR-PAGE-NUMBER>&startdate=<YOUR-START-DATE>&enddate=<YOUR-END-DATE>';
And use $_GET['startdate'] and $_GET['enddate] to retrieve those when processing GET requests.
More about $_POST https://www.php.net/manual/en/reserved.variables.post.php
More about GET AND POST HTTP requests : https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods
There's an error in your isset($_POST['Search'])
your code:
if(isset($_POST['Search'])){
$startdate1 = $_POST['startdate'];
echo "Start date : ".$startdate1", ";
$enddate1 = $_POST['enddate'];
echo "End date : ".$enddate1;
}
possible working solution:
if(isset($_POST['Search'])){
$startdate1 = $_POST['startdate'];
echo "Start date : ".$startdate1.", ";
$enddate1 = $_POST['enddate'];
echo "End date : ".$enddate1;
}
Though I didn't try it yet, but I assume this is the cause, pagination in page2 will not work since the code is not executed after the error which is the pagination for page2.
EDIT: The . fixes things.
echo "Start date : ".$startdate1", ";
is different than
echo "Start date : ".$startdate1.", ";
Add values of your $_POST inside links and use them as $_GET so you would use both.
$startdate1=$enddate1=null; //to hide notice
if(isset($_POST['Search'])){
$startdate1 = $_POST['startdate'];
echo "Start date : ".$startdate1.", ";
$enddate1 = $_POST['enddate'];
echo "End date : ".$enddate1;
} else if (!empty($_GET['startdate']) && !empty($_GET['enddate'])){
$startdate1 = $_GET['startdate'];
echo "Start date : ".$startdate1.", ";
$enddate1 = $_GET['enddate'];
echo "End date : ".$enddate1;
}
$pagLink .= "<li><a href='qm.php?page=".($k+$i)."&startdate=".startdate1."&enddate=".$enddate1."'>".($k+$i)."</a></li>";
For your need:
$pagLink = "";
if($pn>=2){
echo "<li><a href='qm.php?page=1&startdate=".startdate1."&enddate=".$enddate1."'> << </a></li>";
echo "<li><a href='qm.php?page=".($pn-1)."&startdate=".startdate1."&enddate=".$enddate1."'> < </a></li>";
}
for ($i=-4; $i<=4; $i++) {
if($k+$i==$pn)
$pagLink .= "<li class='active'><a href='qm.php?page=".($k+$i)."&startdate=".startdate1."&enddate=".$enddate1."'>".($k+$i)."</a></li>";
else
$pagLink .= "<li><a href='qm.php?page=".($k+$i)."&startdate=".startdate1."&enddate=".$enddate1."'>".($k+$i)."</a></li>";
};
echo $pagLink;
if($pn<$total_pages){
echo "<li><a href='qm.php?page=".($pn+1)."&startdate=".startdate1."&enddate=".$enddate1."'> > </a></li>";
echo "<li><a href='qm.php?page=".$total_pages."&startdate=".startdate1."&enddate=".$enddate1."'> >> </a></li>";
}
That would help you to move dates to next page.
You need to set it to all paging links. Also you can make extra if statement to not pass empty GET
EDIT:
As I already told: You need to set it to all paging links. Also you can make extra if statement to not pass empty GET (that includes javascript)
function go2Page()
{
var pn = document.getElementById("pn").value;
pn = ((pn><?php echo $total_pages; ?>)?<?php echo $total_pages; ?>:((pn<1)?1:pn));
window.location.href = 'teztz.php?page='+pn+'&startdate=<?=startdate1;?>&enddate=<?=$enddate1;?>';
}

I have a PHP shopping cart that is echoing out price and quantity into a table. The ids of each Td are being named p1,p2,p3..etc. and q1,q2,q3..etc. so that I can target them to be used to show total cart cost with javascript. When I try to get the id's value and put it in an alert I get "undefined". I can see that the value is in fact a number so why am I getting undefined? Is there a way to access the value of a Td by its id so that it is not undefined? I would appreciate your help. Will post more code if needed.
var p1= document.getElementById("p1").value;
var q1= document.getElementById("q1").value;
var total= parseFloat(p1) * parseFloat(q1);
window.alert(p1);
Here is the code for this page:

tds don't have values; they have innerTexts. Change these:
var p1= document.getElementById("p1").value;
var q1= document.getElementById("q1").value;
to these:
var p1= document.getElementById("p1").innerText;
var q1= document.getElementById("q1").innerText;
i write 3 example for you
value to get the value from input
innerHTML to get the content
outerHTML To get the content of the whole tag

In my index.php I am fetching data from the database. I put an edit button on that and I have used a datatable to view data information in this form. I have four field: Name, Age, Email, Update through mysqli_fetch_array I have fetched the data.
This is the index.php file:
<?php
//including the database connection file
include_once("config.php");
//fetching data in descending order (lastest entry first)
//$result = mysql_query("SELECT * FROM users ORDER BY id DESC"); // mysql_query is deprecated
// using mysqli_query instead

This is my edit.php file. First I check empty fields, after that I run updating the table query redirecting to the display page. In our case, it is index.php then getting id from url, selecting data associated with this particular id, fetching data through mysqli_fetch_array .
<?php
// including the database connection file
include_once("config.php");
$id = $_POST['id'];
$name = $_POST['name'];
$age = $_POST['age'];
$email = $_POST['email'];
// checking empty fields
if (empty($name) || empty($age) || empty($email)) {
if (empty($name)) {
echo "<font color='red'>Name field is empty.</font><br/>";
}
if (empty($age)) {
echo "<font color='red'>Age field is empty.</font><br/>";
}
if (empty($email)) {
echo "<font color='red'>Email field is empty.</font><br/>";
}
} else {
//updating the table
$result = mysqli_query($mysqli, "UPDATE users SET name='$name',age='$age',email='$email' WHERE id=$id");
//redirectig to the display page. In our case, it is index.php
header("Location: index.php");
}
//getting id from url
$id = $_GET['id'];
//selecting data associated with this particular id
$result = mysqli_query($mysqli, "SELECT * FROM users WHERE id=$id");
while ($res = mysqli_fetch_array($result)) {
$name = $res['name'];
$age = $res['age'];
$email = $res['email'];
}
?>

Finally, this is my edit.js file. In this file I try to do edit the form through AJAX, but I can't find where I doing mistakes.
<script>
$(document).ready(function (e) {
$('#update').click(function (event)
{
event.preventDefault();
$.ajax({
data: $('form').serialize(),
url: "edit.php", //php page URL where we post this data to save in database
type: 'POST',
success: function (strMessage) {
$('#message').text("strMessage");
}
})
});
});
</script>
You are doing edit and update on same file so you have to add condition on file. change your code as below:
edit.php
<?php
// including the database connection file
include_once("config.php");
if($_SERVER['REQUEST_METHOD'] == "POST")
{
$id = $_POST['id'];
$name = $_POST['name'];
$age = $_POST['age'];
$email = $_POST['email'];
// checking empty fields
if(empty($name) || empty($age) || empty($email)) {
if(empty($name)) {
echo "<font color='red'>Name field is empty.</font><br/>";
}
if(empty($age)) {
echo "<font color='red'>Age field is empty.</font><br/>";
}
if(empty($email)) {
echo "<font color='red'>Email field is empty.</font><br/>";
}
} else {
//updating the table
$result = mysqli_query($mysqli, "UPDATE users SET name='$name',age='$age',email='$email' WHERE id=$id");
//redirectig to the display page. In our case, it is index.php
header("Location: index.php");
}
}
//getting id from url
$id = $_GET['id'];
//selecting data associated with this particular id
$result = mysqli_query($mysqli, "SELECT * FROM users WHERE id=$id");
while($res = mysqli_fetch_array($result))
{
$name = $res['name'];
$age = $res['age'];
$email = $res['email'];
}
?>

I hope someone can help me to find the error, I've been stuck here for hours. Thank you.
So here we go. I have a page that lists a bunch of unscored sports games. Here is the query I run to generate the page.
<div id="NFL">
<?php
foreach ($conn->query("SELECT * FROM game_data WHERE sport='NFL' AND awayscore IS NULL ORDER BY date DESC") as $NFL) {
echo '<form method="post" action="update_score.php">
<table class="table table-bordered">
';
echo '
<thead>
<tr>
<th width="5%" class="head0">Rotation</th>
<th width="45%" class="head1">Team</th>
<th width="10%" class="head0">Money Line</th>
<th width="10%" class="head1">Spread</th>
<th width="10%" class="head0">Over/Under</th>
<th width="10%" class="head1">Score</th>
</tr>
</thead>';
echo '
<tr>
<td colspan="6">
';
$date = date_create($NFL['date']);
echo date_format($date, 'l F jS Y \# g:iA');
echo '
</td>
</tr>';
echo '
<tr>
<td>'.$NFL['awayrotation'].'</td>
<td>'.$NFL['awayteam'].'</td>
<td>'.$NFL['awaymoneyline'].'</td>';
echo '
<td>
';
if ($NFL['awaymoneyline'] > 0) {
$line = $NFL['line'] * -1;
echo $line;
}
elseif ($NFL['awaymoneyline'] < 0) {
echo $NFL['line'];
} ;
echo '
</td>';
echo '
<td>'.$NFL['total'].'</td>
<td><input type="text" required name="awayscore"></input></td>
</tr>';
echo '
<tr>
<td>'.$NFL['homerotation'].'</td>
<td>'.$NFL['hometeam'].'</td>
<td>'.$NFL['homemoneyline'].'</td>';
echo '

';
if ($NFL['homemoneyline'] > 0) {
$line = $NFL['line'] * -1;
echo $line;
}
elseif ($NFL['homemoneyline'] < 0) {
echo $NFL['line'];
} ;
echo '
</td>';
echo '
<td>'.$NFL['total'].'</td>
<td><input type="text" required name="homescore"></input></td>
</tr>';
echo '
<tr><td colspan="6" align="right"><input type="hidden" name="id" value="'.$NFL['id'].'"><span style="padding-right:15px"><input type="submit" value="Submit Score"></span></td></tr>
</table>
</form>';
}
?>
</div>
This is what I'm looking to do, I would like to have a button to submit multiple forms. Only though if they have placed a value in the score. Is this possible? I have read about doing multiple forms based off names but these forms are being created dynamically. I look forward to your insight.
here try this
I placed a counter that increments by one per SQL result processed This will also be a key we will use later
The counter is now added to the end of the name fields of the inputs (in front of a "-" to be exploded later)
At the bottom of the script is a little code how I would handle the back end information
<?php
$count = "0";
echo '<form method="post" action="update_score.php"><table class="table table-bordered">';
foreach ($conn->query("SELECT * FROM game_data WHERE sport='NFL' AND awayscore IS NULL ORDER BY date DESC") as $NFL) {
$count = $count+1;
echo '<thead>
<tr>
<th width="5%" class="head0">Rotation</th>
<th width="45%" class="head1">Team</th>
<th width="10%" class="head0">Money Line</th>
<th width="10%" class="head1">Spread</th>
<th width="10%" class="head0">Over/Under</th>
<th width="10%" class="head1">Score</th>
</tr></thead>';
echo '<tr><td colspan="6">';
$date = date_create($NFL['date']);
echo date_format($date, 'l F jS Y \# g:iA');
echo '</td></tr>';
echo '<tr><td>'.$NFL['awayrotation'].'</td><td>'.$NFL['awayteam'].'</td><td>'.$NFL['awaymoneyline'].'</td>';
echo '<td>';
if ($NFL['awaymoneyline'] > 0) {
$line = $NFL['line'] * -1;
echo $line;
}
elseif ($NFL['awaymoneyline'] < 0) {
echo $NFL['line'];
} ;
echo '</td>';
echo '<td>'.$NFL['total'].'</td><td><input type="text" required name="awayscore-$count"></input></td></tr>';
echo '<tr><td>'.$NFL['homerotation'].'</td><td>'.$NFL['hometeam'].'</td><td>'.$NFL['homemoneyline'].'</td>';
echo '<td>';
if ($NFL['homemoneyline'] > 0) {
$line = $NFL['line'] * -1;
echo $line;
}
elseif ($NFL['homemoneyline'] < 0) {
echo $NFL['line'];
} ;
echo '</td>';
echo '<td>'.$NFL['total'].'</td><td><input type="text" required name="homescore-$count"></input></td></tr>';
echo '<tr><td colspan="6" align="right"><input type="hidden" name="id-$count" value="'.$NFL['id'].'"><span style="padding-right:15px">';
}
echo '<input type="hidden" name="count" value="$count">'
echo '<input type="submit" value="Submit Score"></span></td></tr></table></form>'
// back end
$counter = 0;
while ($counter++ < $_POST['count'])
{
$name = $_POST["name-$counter"];
$awayscore = $_POST["awayscore-$counter"];
$homescore = $_POST["homescore-$counter"];
$id = $_POST["id-$counter"]; // considering you may need to get rid of the count
$name = explode("-", $name);
$name = $name[0];
// ect ect
// enter in to data base
//clear all data in strings
}
?>
Sorry about that this was due to haters :|
more to the point yes the back end code is for your passer (the code the form is pointed at)
NB: your PHP style is older than what most use now, close to what I use - just check that all tutorials you use give you references to PHP 5.3 and when in doubt go to php.net and check the function calls for version use - syntax and alternate options
Why is it that I cant pass a value from my PHP code to an OnClick function on my button to my javascript function depCheck2()? I would like to redirect it to 2 different pages depending on the value it carries. Could anyone please help me?
<html>
<head>
<?php
$company_id = $_GET['cont'];
$query = "SELECT count(Department_ID) as countDep FROM department WHERE Company_ID=$company_id";
$result = mysql_query($query, $db) or die(mysql_error($db));
$row = mysql_fetch_array($result);
extract($row);
?>
<script>
function depCheck2(x){
var CountRow = '<?php echo "$countDep";?>';
if (CountRow>0){
window.location.assign("editEvent.php?id="+x"");
}
else{
window.location.assign("editEvent.php2?id="+x"");
}
}
</script>
</head>
<body>
<?php
include("config.php");
$company_id = $_GET['cont'];
$query = "select * from event_details where Company_ID=".$company_id." ORDER BY EventDetails_ID DESC";
$result=mysql_query($query, $db) or die(mysql_error($db));
echo "<table border=1 width='1000'>";
echo "<tr><th>Serial Number</th><th>Status</th><th>Event Type</th><th>Date of Event</th><th>End Date</th><th>Details</th></tr>";
while ($row = mysql_fetch_array($result))
{
extract($row);
echo "
<tr>
<td align='center'>$EventDetails_ID</td>
<td align='center'>$Status</td>
<td align='center'>$EventType</td>
<td align='center'>$StartDate</td>
<td align='center'>$EndDate</td>
<td align='center'>
<input type='button' value='Details' class='btn btn-large btn-primary' onClick='depCheck2(\''.$EventDetails_ID.'\')'>
</td>
</tr>
";
}
?>
</table>
</body>
</html>
At first: <?php echo "$countDep";?> contains $countDep which is not defined in PHP.
It is only present in the DB Query but you haven't assigned it to any variable from the $result
Then window.location.assign("editEvent.php?id="+x""); the syntax is wrong.
You have extra quotes at the end.
It should be window.location.assign("editEvent.php?id="+x);
Try this one:
window.location.href ="editEvent.php2?id="+x;
