First lemme tell you what i am trying to achieve here . Suppose there is a url like this http://www.example.com/?id=12345 now what i want is if there is an id parameter available in the url i want to append the same parameter to every url on that page . Opencart has a url library that generates url i am sure you all must be familiar with it too , i found a way to do what i want but it's working at just some random parts of the website like categories url's are generating with id parameter appended to it and other's dont .
here's what i tried so far
File : System/libray/url.php
here's the function
public function link($route, $args = '', $connection = 'NONSSL') {
if ($connection == 'NONSSL') {
$url = $this->url;
}else {
$url = $this->ssl;
}
$url .= 'index.php?route=' . $route;
if ($args) {
$url .= str_replace('&', '&', '&' . ltrim($args, '&'));
}
foreach ($this->rewrite as $rewrite) {
$url = $rewrite->rewrite($url);
}
if(isset($_GET['id']))
{
if(!empty($this->request->get['id']))
$url .= '&id='.$this->request->get['id'];
if(!empty($_GET['id']))
{
$url .= '&id='.$_GET['id'];
}
}
return $url;
}
The problem is that not everything uses this method to generate its URLs.
For example, anything to do with banners (e.g. the Carousel module) uses links that the admin sets manually in System->Design->Banners, so you would also need to edit the code for this too. The simplest and probably the correct way is to edit the data that the models spit out e.g.
model_design_banner->getBanner() becomes
public function getBanner($banner_id) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "banner_image bi LEFT JOIN " . DB_PREFIX . "banner_image_description bid ON (bi.banner_image_id = bid.banner_image_id) WHERE bi.banner_id = '" . (int)$banner_id . "' AND bid.language_id = '" . (int)$this->config->get('config_language_id') . "'");
if (isset($_GET['id'])) {
array_walk($query->rows, function(&$value) {
$value['link'] .= '&id=' . $_GET['id'];
});
}
return $query->rows;
}
It's either that, or edit the output in every single controller that uses this method.
That's just an example for banners, though. I don't recall off-hand which other modules will need to be edited, but if there's a particular one that's making you scratch your head, let me know and I'll give you another example to fix it.
This is my javascript function.
<script>
function output($file_name, $content)
{
document.getElementById("content_title").innerHTML=" "+$file_name;
document.getElementById("content").innerHTML=" "+$content;
}
</script>
This is my PHP code;
<?php
$dir = "img_png";
$files = scandir($dir);
$dir_length = count($files);
?>
This is the second part of my PHP code (with problem); Problem: When $content="any string"; everything works properly, but when $content=file_get_contents('file'); my triggered function doesn't change any .innerHTML elements at all.
<?php
for ($i=2;$i<$dir_length;$i++){
$title=explode(".png", $files[$i]);
$content=file_get_contents('./content_txt/tv.txt');
echo "<td><button id='button' class='button' onClick=\"output('", $title[0],"";
echo "', '", $content,"";
echo "')\"><img src=\"/img_png/", $files[$i], "\"></img></button></td>";
}
?>
Start solving your issue with this (use dots instead of commas to concatenate strings)
<?php
for ($i=2;$i<$dir_length;$i++){
$title=explode(".png", $files[$i]);
$content=file_get_contents('./content_txt/tv.txt');
echo "<td><button id='button' class='button' onClick=\"output('" . $title[0];
echo "', '" . $content;
echo "')\"><img src=\"/img_png/" . $files[$i] . "\"></img></button></td>";
}
?>
Also I would set $content-variable outside the loop and skip the end-tag (it doesn't make any difference because </img> is not used):
Also encode your data when sending from php (with urlencode)
<?php
$content=file_get_contents('./content_txt/tv.txt');
for ($i=2;$i<$dir_length;$i++){
$title=explode(".png", $files[$i]);
echo "<td><button id='button' class='button' onClick=\"output('" . $title[0];
echo "', '" . urlencode($content);
echo "')\"><img src=\"/img_png/" . $files[$i] . "\"></button></td>";
}
?>
In your javascript you have to decode the content:
function output($file_name, $content)
{
$content = decodeURI($content);
document.getElementById("content_title").innerHTML=" "+$file_name;
document.getElementById("content").innerHTML=" "+$content;
}
Your file contents may contain line breaks or special characters that need escaping in JS, you will need to escape special characters before passing the string to the javascript function.
"tvvvvvv";
I suppose you copy-paste that string from PHP to tv.txt
Remove " and ; - you don't need it in file.
And " is your problem in javascript.
This is a followup to the solution for this question.
I am using jQuery's load() function to pull a headline within a div tag from one page to another within my site. This works wonderfully.
The problem is, load() also pulls the div tag itself, which I do not want, as it then gets formatted via CSS like the source page.
Here is the PHP:
function get_team_articles($team_id, $feat=0) {
.
.
.
while ($row = mysql_fetch_assoc($r)) {
$page = explode('_', $row['page_id']);
(is_numeric($page[1]))
? $pre = 'wk_'
: $pre = '';
$arr[] = $page[0] . " | " . $pre . $page[1] . ": " . "
<a linked_div='news_header'
linked_path='../news/" . $page[0] . "/" . $pre . $page[1] . "/" . $page[1] . "_" . $page[2] . ".html'
href='index.php?view=news&yr=" . $page[0] . "&wk=" . $page[1] . "&pg=" . $page[2] . "'></a>";
}
$articles = implode('<br/>', $arr);
return $articles;
}
Notice the linked_div and linked_path attributes within the anchor tag, which are used in my jQuery:
function set_team_headlines(){
$('#section-articles > a').each(function() {
var a = $(this);
a.load(a.attr('linked_path') + ' #' + a.attr('linked_div'));
});
}
Obviously I cannot strip the HTML tags within the anchor tags in PHP, because the server doesn't have the text within the anchor tags upon loading; so I assume I need to strip the HTML in jQuery after the load() call...and that is what I cannot figure out how to do. :)
The result I want is:
My headline
The result I'm getting is:
<div id="news_header">My headline</div>
Hopefully this makes sense. I think I provided more detail than I needed to. Thanks!
Navigate down one more level in your .load selector
a.load(a.attr('linked_path') + ' #news_header');
If your news_header id isn't unique, it isn't valid to select by that id (ID's must be unique!)
To get around that issue, use this:
a.load(a.attr('linked_path') + ' #' + a.attr('linked_div') + ' div');
Edit:
.load actually includes the targeted element when appending html instead of appending the target element's children. I would move to using $.get().
$.get(a.attr('linked_path')).done(function(html) {
a.text($(html).filter("#news_header").text());
});
I have a huge list of stuff for a glossary ( about 17 pages worth ) that I have to put into an XML file. So I decided I'd use php to make it. My code works, except where ALL the XML code is, it doesn't show because it's trying to render it. Help?
$arg=explode("\n", $strang);
echo count($arg);
for ($i=0;$i<=count($arg);$i=$i+3)
{
echo "<word id='" . $arg[$i+1] . "'>";
echo "<desc>" . $arg[$i] . " - " . $arg[$i+2] . "</desc>";
echo "<pic></pic>";
echo "<audio></audio>";
}
I assume by render it you mean in your browser? If so, you'll need to escape the characters so they will be interpreted literally rather than as markup.
Check out htmlspecialchars and htmlentities
use CDATA construction:
echo "<desc><![CDATA[" . $arg[$i] . " - " . $arg[$i+2] . "]]></desc>";
If this is your entire script, fastest way would probably be to swap all of the <'s with <
$arg=explode("\n", $strang);
echo count($arg);
for ($i=0;$i<=count($arg);$i=$i+3)
{
echo "<word id='" . $arg[$i+1] . "'>";
echo "<desc>" . $arg[$i] . " - " . $arg[$i+2] . "</desc>";
echo "<pic></pic>";
echo "<audio></audio>";
}
Is there any native PHP function as highlight_string(); but for javascript ?
Or, if not, is there any PHP function (homemade) to do it?
EDIT: I want to use PHP function to COLORIZE javascript
I have had great success with GeSHi. Easy to use and integrate in your app and it supports a lot of languages.
I understand you want a Syntax Highligher written in PHP. This one (Geshi) has worked for me in the past:
http://qbnz.com/highlighter/
Yes, the PHP function highlight_string() is a native PHP function for PHP.
No.
But there are a lot of javascript libraries that do syntax-highlight on several languages,
from bash-scripting to php and javascript.
eg, like snippet (JQuery) or jQuery.Syntax (my favorite)
Over here you can find an excellent library which enables syntax highlighting in a large amount of languages using javascripts and a css class.
There is no native php function to do this, so either you have to use existing libraries or you have to write something yourself.
Fastest way - you can use also PHP function "highlight_string" with a little trick
(capture function output and remove leading/trailing PHP tags):
$source = '... some javascript ...';
// option 1 - pure JS code
$htmlJs = highlight_string('<?php '.$source.' ?>', true);
$htmlJs = str_replace(array('<?php ', ' ?>'), array('', ''), $htmlJs);
// option 2 - when mixing up with PHP code inside of JS script
$htmlJs = highlight_string('START<?php '.$source.' ?>END', true);
$htmlJs = str_replace(array('START<span style="color: #0000BB"><?php </span>', ' ?>END'), array('', ''), $htmlJs);
// check PHP INI setting for "highlight.keyword" (#0000BB) - http://www.php.net/manual/en/misc.configuration.php#ini.syntax-highlighting
No native function, but rather than using a full stack library just to highlight some javascript you can use this single function :
function format_javascript($data, $options = false, $c_string = "#DD0000", $c_comment = "#FF8000", $c_keyword = "#007700", $c_default = "#0000BB", $c_html = "#0000BB", $flush_on_closing_brace = false)
{
if (is_array($options)) { // check for alternative usage
extract($options, EXTR_OVERWRITE); // extract the variables from the array if so
} else {
$advanced_optimizations = $options; // otherwise carry on as normal
}
#ini_set('highlight.string', $c_string); // Set each colour for each part of the syntax
#ini_set('highlight.comment', $c_comment); // Suppression has to happen as some hosts deny access to ini_set and there is no way of detecting this
#ini_set('highlight.keyword', $c_keyword);
#ini_set('highlight.default', $c_default);
#ini_set('highlight.html', $c_html);
if ($advanced_optimizations) { // if the function has been allowed to perform potential (although unlikely) code-destroying or erroneous edits
$data = preg_replace('/([$a-zA-z09]+) = \((.+)\) \? ([^]*)([ ]+)?\:([ ]+)?([^=\;]*)/', 'if ($2) {' . "\n" . ' $1 = $3; }' . "\n" . 'else {' . "\n" . ' $1 = $5; ' . "\n" . '}', $data); // expand all BASIC ternary statements into full if/elses
}
$data = str_replace(array(') { ', ' }', ";", "\r\n"), array(") {\n", "\n}", ";\n", "\n"), $data); // Newlinefy all braces and change Windows linebreaks to Linux (much nicer!)
$data = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $data); // Regex identifies all extra empty lines produced by the str_replace above. It is quicker to do it like this than deal with a more complicated regular expression above.
$data = str_replace("<?php", "<script>", highlight_string("<?php \n" . $data . "\n?>", true));
$data = explode("\n", str_replace(array("<br />"), array("\n"), $data));
# experimental tab level highlighting
$tab = 0;
$output = '';
foreach ($data as $line) {
$lineecho = $line;
if (substr_count($line, "\t") != $tab) {
$lineecho = str_replace("\t", "", trim($lineecho));
$lineecho = str_repeat("\t", $tab) . $lineecho;
}
$tab = $tab + substr_count($line, "{") - substr_count($line, "}");
if ($flush_on_closing_brace && trim($line) == "}") {
$output .= '}';
} else {
$output .= str_replace(array("{}", "[]"), array("<span style='color:" . $c_string . "!important;'>{}</span>", "<span style='color:" . $c_string . " !important;'>[]</span>"), $lineecho . "\n"); // Main JS specific thing that is not matched in the PHP parser
}
}
$output = str_replace(array('?php', '?>'), array('script type="text/javascript">', '</script>'), $output); // Add nice and friendly <script> tags around highlighted text
return '<pre id="code_highlighted">' . $output . "</pre>";
}
Usage :
echo format_javascript('console.log("Here is some highlighted JS code using a single function !");') ;
