I want to get first 140 character from the post content and display it into a homepage. I create plugin for that and it doesn't give me the desire out put. Can you guys tell me where I done mistake and how can I recover it? This is the code that I write in plugin file
$length = 140;
function cp_trim_content($length){
$content = explode(' ', get_the_content(), $length );
if( count($content) >= $length)
{
array_pop($content);
$content = implode (" ", $content).'...';
}
else
{
$content = implode (" ", $content);
}
//$content = preg_replace('/\[.+\]/','', $content);
$content = apply_filters('the_content', $content);
return $content;
}
If you want it for 140 character then the below code will work for you
$length = 140;
function cp_trim_content($length)
{
$content = get_the_content();
if(strlen($content)>$length)
{
$final_content = substr($content,0,140).' ...';
}
else
{
$final_content = $content;
}
return $final_content;
}

I have a problem and don't know how to solve it. After i run the code i didn't receive corectly a period of time. I put the code here.
I think something is wrong with table from database (i use PhpMyAdmin 4.2.0 module from EasyPhp). I put an image too to see what happens. The dates marked with red need to be at the end of table.
<?php
function data_range($first, $last, $step = '+1 day', $output - format = 'd-m-Y')
{
$dates = array();
$current = strtotime($first);
$last = strtotime($last);
while ($current <= $last)
{
$dates[] = date($output_format, $current);
$current = strtotime($step, $current);
}
foreach($dates as $zile)
{
$krr = explode('-', $zile);
var_dump($krr);
$result2 = implode('/', $krr);
echo $result2 . "<br/>";
$sql4 = "INSERT INTO studenti3 (data) VALUES ('$result2')";
$rez4 = mysql_query($sql4);
}
var_dump($dates);
}
$first = "06-04-2015";
$last = "07-05-2015";
$step = "+1day";
$output_format = 'd-m-Y';
date_range($first, $last, $step, $output_format); ?>
I'm having a problem with my BB-Code function. I've tested followig input to replace:
Testtext! <b>text<u>testtext</u>test</b><b>test</b>
and get this (mixed) output:
Testtext! [b]text[u]testtext[/u]test</b>test<b>test[/b]
my PHP-Code:
function html_to_bbcode($input) {
$regex[] = '#\<b>((?:[^[]|\<(?!/?b>)|(?R))+)\</b>#im';
$regex[] = '#\<i>((?:[^[]|\<(?!/?i>)|(?R))+)\</i>#im';
$regex[] = '#\<u>((?:[^[]|\<(?!/?u>)|(?R))+)\</u>#im';
if (is_array($input)) {
$tag = explode('>', $input[0]);
$tag = str_replace('<', '', $tag[0]);
if ($tag == 'b') {
$input = '[b]'.$input[1].'[/b]';
} else if ($tag == 'i') {
$input = '[i]'.$input[1].'[/i]';
} else if ($tag == 'u') {
$input = '[u]'.$input[1].'[/u]';
}
}
return preg_replace_callback($regex, 'html_to_bbcode', $input);
}
(and some more Tags)
I can't find that bug :( Have anyone an solution for this?
When reading a excel file, I have problems with numbers greater length:
I use:
try {
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
} catch(Exception $e) {
die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
for ($row = 1; $row <= $highestRow; $row++){
$obj = $sheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, NULL, TRUE, FALSE);
list($CODE, $NAME) = $obj[0];
echo $CODE;
}
And returns 1.6364698338384E+18
Is it possible to obtain 1636469833838380000 ?
I try with
$CODE = (string) floatval($CODE);
... but nothing...
You can change the cell format to text in the excel file and then try reading the values from it.
Hope this helps.
So, I am using Zend to handle my image uploads. This script works well, but I was wondering if there is a way to resize the image that is being uploaded no matter what the current size is. I've seen 2 similar posts, but their code was entirely different, thus would be difficult to translate into mine from theirs. If possible, I would really like to not have to use extensions, but I will if I have to. Any ideas?
if (isset($_POST['upload'])) {
require_once('scripter/lib.php');
//try {
$destination = 'C:\----';
$uploader = new Zend_File_Transfer_Adapter_Http();
$uploader->setDestination($destination);
$filename = $uploader->getFileName(NULL, FALSE);
$uploader->addValidator('Size', FALSE, '10000kB');
$uploader->addValidator('ImageSize', FALSE, array('minheight' => 100, 'minwidth' => 100));
//$pic = $filename;
if (!$uploader->isValid() || $errors) {
$messages = $uploader->getMessages();
} else {
//$pic = $filename;
$no_spaces = str_replace(' ', '_', $filename, $renamed);
$uploader->addValidator('Extension', FALSE, 'gif, png, jpg');
$recognized = FALSE;
if ($uploader->isValid()) {
$recognized = TRUE;
} else {
$mime = $uploader->getMimeType();
$acceptable = array('jpg' => 'image/jpeg',
'png' => 'image/png',
'gif' => 'image/gif');
$key = array_search($mime, $acceptable);
if (!$key) {
$messages[] = 'Unrecognized image type';
} else {
$no_spaces = "$no_spaces.$key";
$recognized = TRUE;
$renamed = TRUE;
}
}
$uploader->clearValidators();
if ($recognized) {
$existing = scandir($destination);
if (in_array($no_spaces, $existing)) {
$dot = strrpos($no_spaces, '.');
$base = substr($no_spaces, 0, $dot);
$extension = substr($no_spaces, $dot);
$i = 1;
do {
$no_spaces = $base . '_' . $i++ . $extension;
} while (in_array($no_spaces, $existing));
$renamed = TRUE;
}
$uploader->addFilter('Rename', array('target' => $no_spaces));
$success = $uploader->receive();
if (!$success) {
$messages = $uploader->getMessages();
} else {
//$pic = $no_spaces;
$uploaded = "$filename uploaded successfully";
$pic = $filename;
if ($renamed) {
$pic = "imgs/upld/" . $no_spaces;
$uploaded .= " and renamed $no_spaces";
//$pic = $no_spaces;
//$pic = $uploader->getFileName(NULL, FALSE);
} else {$pic = "imgs/upld/" . $filename;;}
$messages[] = "$uploaded";
//$pic = $no_spaces;
}
Zend Framework does not ship with a component for handling images.
Good News! PHP has several components that are really good at dealing with all kinds of image issues.
GD (one of those great PHP extensions) is currently shipped as a core extension for PHP, perhaps you will find it useful.
Maybe this will help: http://phpcodeforbeginner.blogspot.com/2013/04/resize-image-or-crop-image-using-gd.html

I've been trying for hours to modify this plugin to work with custom taxonomies instead of post titles and/or post content
http://wordpress.org/extend/plugins/kau-boys-autocompleter/
Added the code / part of the plugin where I think the modification should be done. I could post some stuff I tried but I think it would just confuse people, I don't think I ever came close. Normally I can modify code perfectly but just can't seem to find it. I've tried this method posted here.
http://wordpress.org/support/topic/autocomplete-taxonomy-in-stead-of-title-or-content
But it doesn't work. I've tried searching for possible solutions around his suggestion but I'm starting to think his suggestion isn't even close to fixing it.
