This is sort of confusing to explain, so thank you ahead of time for bearing with me.
I am using Kohana PHP framework to develop an application. I have a model function that accepts parameters for a search, and should return an XML styled page. I need this to be read by the controller with SimpleXML. Any ideas how to do this?
$o = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
$o .= "<feed>\n";
$o .= "\t<search_phrase>$q</search_phrase>\n";
if(isset($entries)){
uasort($entries, 'compare_weight');
/**
* Build the xml data
*/
foreach($modules as $module){
$o .= "\t<search_location>$module</search_location>\n";
}
foreach($entries as $k=>$entry){
$o .= "\n\t<entry>\n";
$o .= "\t\t<title>$entry[title]</title>\n";
$o .= "\t\t<url>$entry[url]</url>\n";
$o .= "\t\t<weight>$entry[weight]</weight>\n";
$o .= "\t\t<module>$entry[module]</module>\n";
if($entry['owners']){
foreach($entry['owners'] as $owner){
$o .= "\t\t<owners>\n";
$o .= "\t\t\t<owner_id>$owner[owner_id]</owner_id>\n";
$o .= "\t\t\t<owner_name>$owner[owner_name]</owner_name>\n";
$o .= "\t\t\t<profile_link>$owner[profile_link]</profile_link>\n";
$o .= "\t\t</owners>\n";
}
}
$o .= "\t</entry>\n";
}
}else{
$o .= "\t<noresult>true</noresult>\n";
}
$o .= "</feed>\n";
return $o;
The controller functions like this... It's the closest I'm able to come to wrapping my head how to do this.
$return= $this->search->search($_GET);
$xml = new SimpleXMLElement($return);
die($xml);
It returns a blank document with 44 blank lines. Any direction would be helpful.
insted of using the constructor of simpleXML try using the simplexml_load_string() function
Try changing the return of your $xml feed to:
return echo $o;

I'm trying to show a object in a html modal. Since I don't know the structure beforehand, and the child properties can also be objects or arrays, a simple recursive function seemed to be the way to go, but Im not sure. I have this:
<?php
class LogHelper extends Helper
{
public function warningLogError($body_error)
{
$data = [];
$html = '';
$html .= "<div name='bodyErrosr' class = 'form-group'>";
$html .= "<div class = 'alert alert-warning' role = 'alert'>";
if (!empty($body_error)) {
foreach($body_error as $key => $value) {
$html .= "<li><b>" . $key . "= " . $value. "</b></li>";
}
} else {
$html .= "<li><b>" . 'Error!' . "</b></li>";
}
$html .= "</ul>";
$html .= "</div>";
$html .= "</div>";
return $html;
}
}
But I don't know the structure beforehand, sometimes I receive an object inside object multiple times. How is the best way to do this?
Have a look at: https://packagist.org/packages/symfony/var-dumper
This also handles circular references (where print_r/vardump fail)
Text:
TestString
HT-Child1 CLASS-Class1
AnotherString
HT-Child2 CLASS-Class2
HT-Child3 CLASS-Class3
HT-Child4 CLASS-Class4
CLASSOFWEEK-Class
What I have so far: (Inside $display->getExtraHTML() is the text). Could someone guide me towards what I need to do to adapt my code to get the results I want.
<?php
$additionalHTML = explode("\n", $display->getExtraHTML());
$html = "";
$html .= "<ul>";
foreach($additionalHTML as $key => $item){
$html .= "<li>$item</li>";
}
$html .= "</ul>";
echo $html;
?>
I know I can use something like this to get string between, but how do I use it to get all the values i need?
$string = strstr($display->getExtraHTML(), "HT-"); // gets all text from HT
$string = strstr($string, "CLASS-", true); // gets all text before CLASS
Can I use both explode and strstr to get to where I want?
Expect HTML markup:
Expected Result: (Get the values from HT- and CLASS-)
<ul>
<li>Child1 Class1</li>
<li>Child2 Class2</li>
<li>Child3 Class3</li>
<li>Child4 Class4</li>
</ul>
Complete solution with preg_match_all function:
$txt = '
TestString
HT-Child1 CLASS-Class1
AnotherString
HT-Child2 CLASS-Class2
HT-Child3 CLASS-Class3
HT-Child4 CLASS-Class4
CLASSOFWEEK-Class';
preg_match_all('/^HT-(\S+)\s+CLASS-(\S+)/m', $txt, $m);
$html = "<ul>";
if (isset($m[1]) && isset($m[2])){
foreach(array_map(null, $m[1], $m[2]) as $pair){
$html .= "<li>". implode(' ', $pair) ."</li>";
}
}
$html .= "</ul>";
echo $html;
The output (push Run code snippet):
<ul><li>Child1 Class1</li><li>Child2 Class2</li><li>Child3 Class3</li><li>Child4 Class4</li></ul>
Here's the solution
<?php
$str = "TestString
HT-Child1 CLASS-Class1
AnotherString
HT-Child2 CLASS-Class2
HT-Child3 CLASS-Class3
HT-Child4 CLASS-Class4
CLASSOFWEEK-Class";
$additionalHTML = explode("\n", $str);
$html = "";
$html .= "<ul>";
foreach($additionalHTML as $key => $item){
if(substr($item,0,3) == "HT-") {
$i = explode(" ",$item);
$a = substr($i[0],3);
$b = substr($i[1],6);
$html .= "<li>$a"." ". "$b</li>";
}
}
$html .= "</ul>";
echo $html;
Result
Child1 Class1
Child2 Class2
Child3 Class3
Child4 Class4
You may use regex, to find the matching lines and extract required data:
if(preg_match("/HT-([A-Za-z0-9]+) CLASS-([A-Za-z0-9]+)/", $item, $output))
{
$html .= "<li>".implode(" ",array_slice($output,1))."</li>";
}
I have a site grabbing Confluence blogpost data. The API im using doesn't appear to have a sort feature. Can anyone help me get PHP sorting the posts on the page by the JSON date, i need the most recent first. Thanks!
<?php
require_once($_SERVER["DOCUMENT_ROOT"].'/layout/layout.inc.php');
require_once($_SERVER["DOCUMENT_ROOT"].'/functions/general.inc.php');
$layout = new my_layout();
$layout->title('IT KB Search');
$layout->content("<div class='border'>");
$layout->content('<h1>IT Support Knowledge Base - Search Results</h1>');
$baseUrl = 'https://website.atlassian.net/wiki';
$url = $baseUrl.'/rest/api/content?spaceKey=KB&type=blogpost&start=0&limit=10&expand=space,history,body.view,metadata.labels';
// To enable authenticated search:
// $url .= "&os_username=$username&os_password=$password";
$response = file_get_contents($url);
$response = json_decode($response);
$results = $response->results;
$html .= '<dl style=list-style: none;>';
foreach($results as $item) {
$date = $item-> history-> createdDate;
$html .= '<strong><a href="';
$html .= $baseUrl. $item-> _links-> webui;
$html .= '" target="_blank">';
$html .= $item->title;
$html .= ' - ';
$html .= date("d/m/Y",strtotime($date));
$html .= '</a></strong><br>';
$html .= $item->body-> view-> value;
$html .= '<br>';
}
$html .= '</dl>';
$layout->content($html);
$layout->content('</div>');
$layout->render();
Before foreach loop, you can use usort like this
usort($results, function ($a, $b) {
return strtotime($a->history->createdDate) - strtotime($b->history-> createdDate);
});
Once done, $result will have data in sorted order $a-$b will give you data in ascending order and $b-$a will give you data in descending order
You can try something like :-
function date_compare($a, $b)
{
$t1 = strtotime($a['datetime']);
$t2 = strtotime($b['datetime']);
return $t1 - $t2;
}
usort($results, 'date_compare');
You can declare the function date_compare in your php file and use the statement:-
usort($results, 'date_compare');
just before the for each loop
I'm in the process of learning php so forgive me if this is a silly question. I'm trying to make a dynamic gallery that looks through a folder(./JIN/snoii/) and produces the html code for the number of items in said folder. This code I've written isnt returning anything when the file has images(currently has over a hundred) can some one tell me where I messed up or point me in the right direction. Thanks in advance
$CurrentViewFile = "snoii";
function showGallery(){
global $CurrentViewFile;
$galleryHTML = "<h1>Dynamic gallery</h1>";
$galleryHTML .= "<ul>";
$folderToview = "JIN/";
$folderToview .= $CurrentViewFile;
$images = new DirectoryIterator($folderToview);
while($images->valid()){
$galleryHTML .= "<li>!!</li>";
$images->next();
}
$galleryHTML .= "</ul>";
return $galleryHTML;
}
return showGallery();
Your DirectoryIterator makes the problem,
Please try like this
$CurrentViewFile = "/snoii";
function showGallery(){
global $CurrentViewFile;
$galleryHTML = "<h1>Dynamic gallery</h1>";
$galleryHTML .= "<ul>";
$folderToview = "JIN/";
$CurrentViewFile .= $folderToview;
foreach (new DirectoryIterator($CurrentViewFile) as $images) {
if($images->valid())
$galleryHTML .= "<li>!!</li>";
$images->next();
}
$galleryHTML .= "</ul>";
return $galleryHTML;
}
$output_data = showGallery();
echo $output_data;
If you want to get file name from the iterator you should use like this,
$images->getFilename()
I am trying to make a own class in CodeIgniter and therefore I have made a file in the folder
libraries
This class is called
Menu
And it contains a class to create a navigation bar for my website. this class is like
class Menu {
public function draw($menu) {
$CI =& get_instance();
$output = '';
foreach ($menu as $key => $value) {
$output .= "<li>";
if (is_array($value)) {
if (strpos($key, '|') !== false) {
$param = explode('|', $key);
$output .= anchor($param[1], $param[0]);
} else {
$output .= anchor('#', $key);
}
$output .= PHP_EOL."<ul>".PHP_EOL;
$output .= draw($value);
$output .= "</ul>".PHP_EOL."</li>".PHP_EOL;
} else {
$output .= anchor($key, $value, $CI->uri->slash_segment(1, 'leading') == $key ? 'class="active"' : '');
$output .= "</li>".PHP_EOL;
}
}
return $output;
}
}
I have put this class in my config file as autoload under libraries
$autoload['libraries'] = array('menu');
When I call the class to use it I do this
<?php
$m = new Menu();
echo $m->draw($menu);
?>
But unfortunately I get this error
Fatal error: Call to undefined function draw() in /Users/username/Sites/infinity2.0/application/libraries/Menu.php on line 22
Line 22 is $output .= draw($value);
But I don't know how to solve this I think its because of calling its own method again.. any help is welcome and appreciated. :)
Change
$output .= draw($value);
to
$output .= $this->draw($value);
$this refers to the current object, so if you want to recursively call draw() within itself, you need to use it to refer to it..
