My piece of code.
And problem now are about styling, i just want style page number, wich is open, like a active id, if page open, then that number is in different color or smth else.
I need make a new variable? Or what, i just try to add but its wont work, it only works if at the end i write echo $page; , then it show style on this, but i need on links, numbers.
<?php
if($total_pages > 1){
if($page != 1){
echo ' < ';
}
for($number=1;$number<=$total_pages;$number++)
{
echo ''.$number.'';
}
if($page != $total_pages){
echo ' > ';
}
}
?>
You can do something like this.
$currentPageNumber = $_GET['page'];
for($number=1;$number<=$total_pages;$number++){
$currentPageStyle = '';
if($number == $currentPageNumber){
$currentPageStyle = 'style="color:red"';
}
echo '<a href="?page='.$number.'" '.$currentPageStyle.'>'.$number.'</a>';
}

how do i tell this php code that, when there's not a ?page=randompage in the url, it will trow the active to index.php automatically?
<?php
$query = "SELECT pagename, pagetitle FROM pages LIMIT 8";
$result = $mysqli->query($query);
echo "<ul>";
while ($row = $result->fetch_array(MYSQLI_ASSOC)){
echo "<li><a href=\"?page=".$row["pagename"]."\"";
if ($_GET['page'] == $row['pagename']) {
echo " class=\"active\""; } echo "> ".$row["pagetitle"]." </a></li>";
}
echo "</ul>";
?>
It's beacuse whenever my url looks like this http://localhost/greencph/ it shows a php error, because it does not know which site it is on, it works perfect as long as the url looks like this: http://localhost/greencph/?page=index.php a detailed explanation on how to fix this problem would be appreciated!
Please remember i'm a idiot, explain to me so i understand it. xD
The error is coming because, every time the value of $_GET is not getting set.
So, to deal with it,
get the value of $_GET['page'] in a variable.
So that, if we do not get $_GET, we will assign it a default value, that is index page.
$page = ! empty($_GET['page']) ? $_GET['page'] : 'index'; // set default value.
And change this line:
if ($page == $row['pagename']) {
So, the final modified code should be:
<?php
$query = "SELECT pagename, pagetitle FROM pages LIMIT 8";
$result = $mysqli->query($query);
$page = ! empty($_GET['page']) ? $_GET['page'] : 'index';
echo '<ul>';
while ($row = $result->fetch_array(MYSQLI_ASSOC)) {
$class = '';
if ($page == $row['pagename']) {
$class = 'active';
}
echo '<li>' . $row["pagetitle"].' </li>';
}
echo "</ul>";
?>
Use the $_GET array:
<?php
if(isset($_GET['page'])) {
// Your code
...
}
?>
Problem is in this line
if ($_GET['page'] == $row['pagename']) {
You're not checking whether the index 'page' even exists. So, when you try to load the page without any GET parameters $_GET['page'] won't be even set and you'll get an error for accessing unset element.
To fix this simply check
if(isset($_GET['page']) {
...your code...
}
if(count($fetchExperiences) > 0)
{
$i=0;
foreach($fetchExperiences as $fetchExperience)
{
$sqlExperiencedat = $db->createCommand(" code ");
$fetchExperiencesdat = $sqlExperiencedat->queryAll();
$tdyyy=date('YYYY-mm-dd');
if(strtotime($tdyyy)<strtotime($fetchExperience['experience_date']))
{
foreach($fetchExperiencesdat as $fetchExperiencesdatt)
{
if(strtotime($tdyyy)<strtotime($fetchExperiencesdatt['avail_date']))
{
//echo $fetchExperiencesdatt['avail_date'];
$tth=1;

<a class="more_experience" style="clear:both;"><span onclick="getMoreExperiences1('<? php echo count($userResults);?>','<?php echo $_SESSION['user_id']; ?>','8')">More Experiences</span></a>
}
}
}
My question is that I want more button after $fetchexperiences count is greater than 8. It is fine. But in between $fetchexperiences loop there is a loop for $fetchExperiencesdat. by the loop if there is no experince with in availdate it is not shown. so the probelm is more button is display not after 8 because of some $fetchExperiencesdat elements should be hidden. So please give me any solution for this.
Thanking you.
I'm not sure I understand where your count experiences are coming from. However, the problem your code has is that fetchCountExperiences is not given a value.
if(count($fetchCountExperiences) > 8){
<a class="more_experience" style="clear:both;"><span onclick="getMoreExperiences1('<? php echo count($userResults);?>','<?php echo $_SESSION['user_id']; ?>','8')">More Experiences</span></a>
}
Looks like it should be
if(count($fetchExperiences) > 8){
<a class="more_experience" style="clear:both;"><span onclick="getMoreExperiences1('<? php echo count($userResults);?>','<?php echo $_SESSION['user_id']; ?>','8')">More Experiences</span></a>
}
I am currently using the plugin WP-CommentNavi for comments pagination but whenever a page is clicked it goes to the highest comments page (oldest comments). My comments are purposely displayed newest first and therefore I need the default pagination page to be 1 whenever a link is clicked.
I notice there is the same default for other pagination plugins too whereby the highest pagination page (ie if there are 5 pages) page 5 is displayed.
At the moment when I load page tellhi####.com/newcastle the page that will be loaded is tellhi####.com/newcastle/comment-page-2/ whereas I want tellhi####.com/newcastle/comment-page-1/ to be loaded
I can't be sure this is the relevant code to what I am trying to achieve but I feel the answer might lie in here (below). If not, please tell me and disregard this code.

In short I need, anytime a page is clicked, for the comments pagination to be on page 1, not the highest page available. Just so you know I have tried the discussion settings on the wordpress dashboard. Nothing on google either!
Failing a full answer, does anyone know the actual php code that determines what pagination page is loaded by default?
I received this response via an e-mail but due to my PHP knowledge am unable to implement it, any ideas? ...
Just reverse the loop. That'll fix it. Here's the relevant part:
http://pastie.org/8166399 You need to go back, i.e. use $i--
Would this change the default start page or just reverse the comments? Hope I have been clear in my question! Will appreciate any response at all.
Thanks in advance, Paul
The option was in Wordpress all along. See picture: http://oi40.tinypic.com/35aj3pt.jpg
If anyone has the answer to the specific code you manipulate, still answer the question here because someone doing this without Wordpress could very well encounter this problem also.
I have a situation whereby i want two of my pages to look different form the rest but they are not front pages. If they were it would be easy as the code below would do the trick.
$menu = & JSite::getMenu();
if ($menu->getActive() == $menu->getDefault()) {
echo 'This is the front page';
esle(do something else)
}
?>
In short i want a similar approach but this time, to get the menu by ID/URL. Any ideas?
I got the answer to this...all you need to check is the menu ID then put the code below.
<?php
//This is the code for the page with menu ID 6
$menuID = JSite::getMenu()->getActive()->id ;
if ($menuID == '6')
{
echo '';
}
elseif ($menuID == '2') //This is the HTML for page with menu ID 2
{
echo '';
}
elseif ($menuID == '4') //THis is the html for page with menu id 4
{
echo '';
}
else //This is the HTML code for the rest of the pages
{
echo '';
}
?>
Page ItemId can be obtained using $itemid = JRequest::getInt( 'Itemid' );
I am using the following code:
$result = mysql_query("SELECT * FROM table LEFT JOIN table2
ON table.field = table2.field WHERE ( table.field = '$pid' )
AND ( table.field5 LIKE '%$q%' OR table.field3 LIKE '%$q%'
OR table2.field2 LIKE '%$q%' )");
if (empty($what)) {
$countpls = "0";
} else {
$countpls = mysql_num_rows($result);
}
<?php
if ($countpls > 10) {
echo '<a id=pgnvg href="' . $_SERVER['PHP_SELF'] . '?pg=' . ($startrow + 20) . '&q=' . ($what) . '">Next</a>';
} else {
echo "";
}
$prev = $startrow - 20;
//only print a "Previous" link if a "Next" was clicked
if ($prev >= 0) {
echo '<a id=pgnvg2 href="' . $_SERVER['PHP_SELF'] . '?pg=' . $prev . '&q=' . ($what) . '">Previous</a>';
} else {
echo "";
}
?>
I want the next to show only if there are more entries to show and previous only if there are more entries to circle back to. It works on the first page bt then on the last page Next shows despite teh fact that there are no more results to show.
I tried adding the 'else' but its still not working.
Any ideas?
if($countpls > 0){
$pg = $_POST['pg']?$_POST['pg']:1;
//if it's not the first page...
if($pg>1){
echo '<a id="pgnvg" href="'.$_SERVER['PHP_SELF'].'?pg='.($pg-1).'&q='.$what.'">Previous</a>';
}
//if you have more registers to show...
if(($countpls-(($pg-1)*10))>10){
echo '<a id="pgnvg" href="'.$_SERVER['PHP_SELF'].'?pg='.($pg+1).'&q='.$what.'">Next</a>';
}
}
In order to calculate your offset to use in queries, use this:
$offset = ($_POST['pg']-1)*10;
It would help if you would provide the code that's setting $countpls. That might be the part that's causing the problem. Also, the else's are unnecessary. However, try this:
if($countpls - $startrow > 20)
{
echo '<a id=pgnvg href="'.$_SERVER['PHP_SELF'].'?pg='.($startrow+20).'&q='.($what).'">Next</a>';
}
I think it would do you good if you followed a tutorial to grasp the basic concepts. It even comes with the example that could either 1.) replace your current pagination or 2.) fix it.
