I have a problem with my pagination script. I have two links on one category:
link 1: abc.com/category.html
link 2: abc.com/category-p2.html
My php script is:
$pagelink = 'abc.com/category';
if($pages > 1)
{
$pagination = '';
$pagination.= '<ul class="paginate">';
for($i = 1; $i<=$pages; $i++)
{
$pagination .= '<li>'.$i.'</li>';
}
$pagination .= '</ul>';
}
I want that: if $i=1, $pagelink is: abc.com/category, not add -p$i before html prefix.
So my new code is:
$pagelink = 'abc.com/category';
if($pages > 1)
{
$pagination = '';
$pagination.= '<ul class="paginate">';
for($i = 1; $i<=$pages; $i++)
{
if($i=1)
{$pagination .= '<li>1</li>';}
else
{$pagination .= '<li>'.$i.'</li>';}
}
$pagination .= '</ul>';
}
But it's seem that it is not working.
Please help me to fix this.
Thanks alot in advance.
One immediate problem jumps out at me:
if($i=1)
should be:
if ($i == 1)

You are not passing a
GET parameter Page
and you are directly referencing it in line 17 $Page = $_GET["Page"];
Ideally for this easy fix will be
if(!$_GET["Page"])
{
$Page=1;
}
else{
$Page = $_GET["Page"];
}
Hope it helps
Happy Coding !!!
You can use php function isset to check a argument "Page" is set.
if (isset($_GET['Page'])) {
$Page = $_GET['Page'];
} else {
$Page = 1
}
You did not pass any "Page" parameter. You can change the code to.
if(!isset($_GET["Page"]))
{
$Page=1;
}
Update these lines
$Page = $_GET["Page"];
if(!$_GET["Page"])
{
$Page=1;
}
With
if(isset($_GET["Page"] && !empty($_GET['Page'])))
{
$Page=$_GET["Page"];;
}else{
$Page=1;
}
There is a problem with my paypal Integration in live site.
For 90% of transactions, I didn't get any problem. Some times only I am facing this below problem.
Problem: After successful transaction, I am not getting Pay pal values like Transaction Id, Message etc. All values shows empty. It comes for 10% of transactions only. please tell me what may be the problem. Can't able to find out the reason

Is there a way to do something like that in a snippet : <?php if ([[+idx]]==1) echo "0";<?
Thank you.
If you need to get the value of a template variable, you can use this
$id = $modx->resource->get('id');//ID of current resource
$name = $modx->resource->get('pagetitle');//title of current resource
$val = $modx->resource->getTVValue('name_of_tv');//get tv value of current resource by name
$val = $modx->resource->getTVValue($tv_id);//get tv value of current resource by ID
To get idx of migx tv you need something like this -
<?php
$docid = $modx->resource->get('id'); // id of curent resource
$tvname = 'name_of_your_tv'; // change to yours
$tv = $modx->getObject('modTemplateVar', array('name' => $tvname));
$outputvalue = $tv->renderOutput($docid);
$items = $modx->fromJSON($outputvalue);
$idx = 0; // initialize idx
$output = array();
foreach ($items as $key => $item) {
$idx++; // increase idx
$output[] = print_r($item,1); // test output
}
$outputSeparator = "\n";
$o = implode($outputSeparator, $output); // implode output
return $o;
Taken from migx snippet https://github.com/Bruno17/MIGX/blob/master/core/components/migx/elements/snippets/snippet.getImagelist.php
since you are probably calling your snippet from the resource in question [are you?] you can just pass the idx to the snippet....
[[!callMySnippet? &idx=[[+idx]] ]]
then in your snippet:
$output = '';
$idx = $scriptProperties['idx'];
if ($idx==1) {
$output = "0";
}
return $output;
Let start with the basic back ground. We recently brought our web hosting in house.
There are few old website still use Perl. I have no experience with Perl.
Let's Begin. We have a this sub website on our main domain.

Please let me know what I am missing. If you need to look at more "included" files let me know.
Also here is the link for our cgi config. http://www.gatewayrehab.org/eap/cgi-bin/cgi.cgi
Thank You.
The error comes from this line: my $summary_ref = $File -> read($login_summary)|| $Error -> display("$!". __LINE__);. It means $Error doesn't exist or its value is undef. And indeed, I don't see such a variable being declared or initialised. Maybe it's suppose to be exported by Error_Handler???
This error is happening when trying to report another error. You could try replacing (if only temporarily) $Error -> display("$!". __LINE__); with die($!) and checking your server's error log for the error message. That said, it's surely "No such file or directory" or "Permission denied", so maybe it's not worth the time to find out the exact message. (Upd: Actually, I think the message will be "redirected" to your browser, so that makes things easier.)
I'm guessing here, but it looks like it's trying to read the file named by $login_summary. I have no idea where this is set (if at all!), so you might want to find out its value, and maybe where it's getting set.
As ikegami pointed out, the error you are seeing indicates that $Error is not being initialized, and looking at the rest of the script, I would guess that what is needed (first of all) is to initialize it in the same manner as the $File and $Cookie variables. Add this line after line 20 in your script:
my $Error = new Error_Handler;
That might give you a nicer error message, but it will probably just tell you what you already discovered when you added your die($!); line: 'No such file or directory'.
Your script is also doing a file called ./cgi-bin/include/common.cgi. Check this file for your $login_summary variable, to know what file it's trying to access.
I have resolved the problem with a quick fix. I don't know why it work but it does for me.
Here what i did...After reading online i found that adding "-w" on the header of all .(dot)cgi files make it work.
I do hope there is a better method to add "-w" in one place then adding it on all .cgi files.
In short change #!/usr/bin/perl to #!/usr/bin/perl -w
Thanks all.
This is the code of my export_to_excel helper:
function export_to_excel($query, $filename='exceloutput')
{
$headers = ''; // just creating the var for field headers to append to below
$data = ''; // just creating the var for field data to append to below
$obj =& get_instance();
$fields = $query->list_fields();
if ($query->num_rows() == 0) {
echo '<p>The table appears to have no data.</p>';
} else {
foreach ($fields as $field) {
$headers .= $field . "\t";
}
foreach ($query->result() as $row) {
$line = '';
foreach($row as $value) {
if ((!isset($value)) OR ($value == "")) {
$value = "\t";
} else {
$value = str_replace('"', '""', $value);
$value = '"' . $value . '"' . "\t";
}
$line .= $value;
}
$data .= trim($line)."\n";
}
$data = str_replace("\r","",$data);
header("Content-type: application/x-msexcel; charset=utf-8");
header("Content-Disposition: attachment; filename=$filename.xls");
echo "$headers\n$data";
}
}
I get different results in localhost and on server. When I run the code in localhost, it outputs the proper result with no problem, but when I run the code on server, it gives the same result as in localhost, but it adds two more lines (excel rows) containing error as follows:
<br />
<b>Fatal error</b>: ob_start()
[< a href='ref.outcontrol'> ref.outcontrol</a>]:
Cannot use output buffering in output buffering display handlers in
<b>/home/username/public_html/Codeigniter_website/system/core/Exceptions.php</b>
on line <b>181</b><br />
Any solutions?
It's almost a large project and it's the only difference that I have seen between local and server.
The solution is to make sure output and parsing stops after the desired output.
The can be done by putting exit; after echo "$headers\n$data";
