Eclipsu nu se porneste
In eclipse.ini bagam dupa:
openFile
–launcher.appendVmargs
bagam:
-vm
C:\Program Files\Java\jdk1.8.0_31\bin\javaw.exe
sau deja calea la Java instalat pe calck, ar trebui sa mearga acum.
Eclipse merge aiurea.
Solutia ce am gasito eu:
Project -> proprietes -> PHP -> Buld path -> si bagam in exclude toate fisierele eclipsului din project, adica cele cu “.” in fata.
Instalam FFMpeg si FFMPEG-PHP Extension pe Centos
yum install ffmpeg ffmpeg-devel
If you get package not found, then you will need to add few lines in the yum repository for dag packages installation. Create a file named dag.repo in /etc/yum.repos.d with the following contents on it
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1
then
yum install ffmpeg ffmpeg-devel
daca are probleme cu keia sau ceva de genu asta eu am rezolvata asa:
rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt
astea(http://www.mysql-apache-php.com/ffmpeg-install.htm) zic asa:
rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
Install FFMPEG-PHP Extension
wget http://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2
tar -xjf ffmpeg-php-0.6.0.tbz2
cd ffmpeg-php-0.6.0/
phpize
daca nu e instalat: yum install php-devel
./configure
Daca zice ceva cu no acceptable C compiller PATH bla bla, ii dam asa: yum groupinstall "Development tools"
make
Daca da eroare de genu: "ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: Б─≤PIX_FMT_RGBA32Б─≥ undeclared (first use in this function)", facem asa:
Fix: With the latest version of ffmpeg-php (0.6.0), update ffmpeg_frame.c and replace every instance of PIX_FMT_RGBA32 with PIX_FMT_RGB32
vi ffmpeg_frame.c
:%s/PIX_FMT_RGBA32/PIX_FMT_RGB32
:w :q!
./configure
make
make install
WP n-a generat _wp_attachment_metadata pentru fisiere media.
Nu stiu din ce cauza nu sau generat(din cauza asta imaginile in admin -> media nu se afiseaza ca se pune atributul width si height egal cu 1), dar ca sa le generez din nou am facut un script de reparare:
in wp-includes/post.php dupa linia 4250, ce contine
$data = get_post_meta( $post->ID, '_wp_attachment_metadata', true );
am adaugatun cod de verificare:
if (!$data){
$file_name = str_replace('http://domeniu.com/wp-content/uploads/', WP_CONTENT_DIR . '/uploads/', $post -> guid);
$attach_data = wp_generate_attachment_metadata( $post->ID, $file_name);
wp_update_attachment_metadata( $post->ID, $attach_data );
$data = get_post_meta( $post->ID, '_wp_attachment_metadata', true );
}
iar acum doar parcurgem toata galeria media ca sa se genereze datele pentru toate imaginile.
WP – schimbam domeniul sau directorul.
Exista cazuri cand tre sa mutam un wordperss platforma de pe un domeniu pe altl, sau pe acelas domeniu in alt director, ca sa mearga pe nou tre sa updatam baza de date:
UPDATE wp_options SET option_value = REPLACE(option_value,'www.olddomain.com','www.newdomain.com') WHERE option_name = "siteurl" OR option_name = "home"; UPDATE wp_posts SET post_content = REPLACE(post_content,'www.olddomain.com','www.newdomain.com');
Export fisier in UTF8 format
Atunci cand avem treaba cu diacritice, sau caractere speciale ne intimpinam cu tot felul de probleme la codificare, una dintre care este export a datelor in fisier, ca sa se exporte corect si editorul in care se va deschide fisierulk sa stie ca e format utf8 facem asa:
header ('Content-Type: application/download');
header('Expires: 0');
header('Cache-Control: private');
header('Pragma: cache');
header ('Content-Transfer-Encoding: binary');
header('Content-Encoding: UTF-8');
header('Content-type: text/csv; charset=UTF-8');
//header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv; filename=" . date("Y-m-d") .".csv; size=".strlen($sExportContent));
echo "\xEF\xBB\xBF"; \\Ii zice editorului ca e fisier in format UTF-8
print $sExportContent;
exit;
Ecranam caracterile nestandard.
O facem cu htmlspecialchars nu cu htmlentities.
UTF-8 pe site
Ca sa nu avem probleme cu diacritice, chirilica, si alte caractere nestandarte facem urmatoarele:
In HEAD bagam:
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
In cod php bagam la inceput:
mb_internal_encoding('UTF-8');
mb_http_output('UTF-8');
mb_http_input('UTF-8');
mb_language('uni');
mb_regex_encoding('UTF-8');
//ob_start('mb_output_handler'); - aici tre de vazut daca e bine sau nu cu asta
La creare baza de date facem asa:
CREATE DATABASE mydatabase CHARACTER SET utf8 COLLATE utf8_Unicode_ci;
Iar la conectare la baza de date setam urmatoarele:
SET NAMES utf8;
SET CHARACTER SET utf8;
Probleme n-ar trebui sa mai apara…
P.S. : Daca pina acum campurile erau latin si contineau caractere speciale, sa nu le perdem pentru fiecare camp in parte tre sa exacutam urmatorul query:
UPDATE `tabel` SET <field> = convert(binary convert(<field> using latin1) using utf8);
