So right now, I have a simple function that I use to call some text content:
function htmlstuff() { ?>
<p>html text content here</p>
<? }
And on a page I call the text using:
<?php htmlstuff() ?>
Now, I need to figure out how to use "search and replace" for whatever text is in the function. I've tried things like
function str_replace($search,$replace,htmlstuff())
but I obviously don't know what the heck I'm doing. Is there any simple way to just search the text within the function and search/replace?
what do you really want to do?
if you want to search and replace and in the return variable of your htmlstuff function then
you are not too far away from the correct answer.
function htmlstuff() {
$htmlstuff = "<p>html text content here</p>";
return $htmlstuff;
}
echo htmlstuff();
str_replace($search,$replace,htmlstuff());
this should do the trick
if you just want to make the function htmlstuff more dynamic, then you should take a different approach. something like this:
function htmlstuff($html) {
$htmlstuff = "<p>".$html."</p>";
return $htmlstuff;
}
echo htmlstuff("html text content here");
It would seem like this:
function htmlstuff ($content = "Default text goes here")
{
echo "<p>" . $content . "</p>";
}
and then on another call you just htmlstuff("New text to go there");
And if I'm wrong correct me to solve the problem
<?php
$html_stuff = htmlstuff();
$search_for = "Hello, world!";
$replace_with = "Goodbye, world!";
$html_stuff = str_replace($search_for, $replace_with, $html_stuff);
echo $html_stuff;
function htmlstuff() {
echo '<p>html text content here</p> ';
}

I've searched around and around and I'm not sure how this really works.
I have the tags
<taghere>content</taghere>
and i want to pull the "content" so i can put an ifstatement depending on what the "content" is as the "content" is varrying depending on the page
i.e
<taghere>HelloWorld</taghere>
$content = //function that returns the text between <taghere> and </taghere>
if($content == "HelloWorld")
{
//execute function;
}
else if($content =="Bonjour")
{
//execute seperate function
}
i tried using preg but it doesnt seem to work and just returns whatever value is in the lines field instead of actually giving me the information within the tags
If I understand your question correctly, you want the data INSIDE the tag "taghere".
If you are parsing HTML, you should use DOMDocument
Try something similar to this:
<?php
// Assuming your content (the html where those tags are found) is available as $html
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html); // loads your HTML
libxml_clear_errors();
// Note: Tag names are case sensitive
$text = $dom->getElementsByTagName('taghere');
// Echo the content
echo $text
you can use DomDocument and loadXML to do this
<?php
function doAction($word=""){
$html="<taghere>$word</taghere>";
$doc = new DOMDocument();
$doc->loadXML($html);
//discard white space
$hTwo= $doc->getElementsByTagName('taghere'); // here u use your desired tag
if($hTwo->item(0)->nodeValue== "HelloWorld")
{
echo "1";
}
else if($hTwo->item(0)->nodeValue== "Bonjour")
{
echo "2";
//execute seperate function
}
}
doAction($word="Bonjour");
You cannot do it like that. Technically it is possible but it's more than an overkill. And you mixed up PHP with HTML in a way that doesn't work.
To achieve the thing that you want you have to do something like this:
$content = 'something';
if ($comtent === 'something') {
//do something
}
if ($content === 'something else') {
//do something else
}
echo '<tag>'. $content . '</tag>' ;
Of course you can change $content in the ifs.
Dont forget, you can allways add an ID into a tag so you can reference it with java script.
<tag id='tagid'>blah blah blah </tag>
<script>
document.getElementById(tagid)
</script>
This might be a much simpler way to get what you are thinking about then some of the other responses
I don't know what regex you tried and therefor not what would have been wrong. Might have been the escaping of the <
<?php
if(preg_match('#\<taghere>(.*)\</taghere>#', $document, $a)){
$content = $a[1];
}
?>
I suppose there will be only one
This block of PHP code prints out some information from a file in the directory, but I want the information printed out by echo to be used inside the HTML below it. Any help how to do this? Am I even asking this question right? Thanks.
if(array_pop($words) == "fulltrajectory.xyz") {
$DIR = explode("/",htmlspecialchars($_GET["name"]));
$truncatedDIR = array_pop($DIR);
$truncatedDIR2 = ''.implode("/",$DIR);
$conffile = fopen("/var/www/scmods/fileviewer/".$truncatedDIR2."/conf.txt",'r');
$line = trim(fgets($conffile));
while(!feof($conffile)) {
$words = preg_split('/\s+/',$line);
if(strcmp($words[0],"FROZENATOMS") == 0) {
print_r($words);
$frozen = implode(",", array_slice(preg_split('/\s+/',$line), 1));
}
$line = trim(fgets($conffile));
}
echo $frozen . "<br>";
}
?>
The above code prints out some information using an echo. The information printed out in that echo I want in the HTML code below where it has $PRINTHERE. How do I get it to do that? Thanks.
$("#btns").html(Jmol.jmolButton(jmolApplet0, "select atomno=[$PRINTHERE]; halos on;", "frozen on")
You just need to make sure that your file is a php file..
Then you can use html tags with php scripts, no need to add it using JS.
It's as simple as this:
<div>
<?php echo $PRINTHERE; ?>
</div>
Do remember that PHP is server-side and JS is client-side. But if you really want to do that, you can pass a php variable like this:
<script>
var print = <?php echo $PRINTHERE; ?>;
$("#btns").html(Jmol.jmolButton(jmolApplet0, "select atomno="+print+"; halos on;", "frozen on"));
</script>
I am working on a script with templates. So I have this PHP code:
<?php
$string = "TEST";
echo(file_get_contents('themes/default/test.html'));
?>
And I have this HTML (the test.html file):
<html>
<p>{$string}</p>
</html>
How can I make PHP actually display the variable inside the curly brackets? At the moment it displays {$string}.
P.S:
The string might also be an object with many many variables, and I will display them like that: {$object->variable}.
P.S 2: The HTML must stay as it is. This works:
$string = "I'm working!"
echo("The string is {$string}");
I need to use the same principle to display the value.
You can use the following code to achieve the desired result:
<?php
$string = "TEST";
$doc = file_get_contents('themes/default/test.html'));
echo preg_replace('/\{([A-Z]+)\}/', "$$1", $doc);
?>
P.S. Please note that it will assume that every string wrapped in { }
has a variable defined. So No error checking is implemented in the code above. furthermore it assumes that all variables have only alpha characters.
If it is possible to save your replacees in an array instead of normal variables you could use code below. I'm using it with a similar use case.
function loadFile($path) {
$vars = array();
$vars['string'] = "value";
$patterns = array_map("maskPattern", array_keys($vars));
$result = str_replace($patterns, $vars, file_get_contents($path));
return $result;
}
function maskPattern($value) {
return "{$" . $value . "}";
}
All you PHP must be in a <?php ?> block like this:
<html>
<p><?php echo "{" . $string . "}";?></p>
</html>
If you know the variable to replace in the html you can use the PHP function 'str_replace'. For your script,
$string = "TEST";
$content = file_get_contents('test.html');
$content = str_replace('{$string}', $string, $content);
echo($content);
It's simple to use echo.
<html>
<p>{<?php echo $string;?>}</p>
</html>
UPDATE 1:
After reading so many comments, found a solution, try this:
$string = "TEST";
$template = file_get_contents('themes/default/test.html', FILE_USE_INCLUDE_PATH);
$page = str_replace('{$string}',$string,$template);
echo $page;
I have this issue with my jquery code:
<?php
//I oppen a text document, read the text inside of it and write it inside my html page.
//When someone clicks on a line, I want to take that very same line and send it via select(String) function.
$handle = fopen($_POST['lien'], 'r');
if ($handle)
{
while (!feof($handle))
{
$buffer = fgets($handle);
echo "<div onclick='select(\" ".$buffer." \");'>".$buffer."</div><br/>";
//It works when I put a simple string within the select param:
//echo "<div onclick='select(\" text \");'>".$buffer."</div><br/>";
}
fclose($handle);
}
?>
The jquery code :
function select(text){
alert(text);
//$("#selected").html();
}
where do you guys think is the problem ?
Thanks :)
Maybe Your $buffer contains some double-quotes, which then interfere with surrounding double-quotes. Look at produced HTML code if this is the case, maybe You'll see something like this:
<div onclick='select("He said: "Freeze!"")'>
... which Javascript can't parse correctly. If this is the case, consider using:
echo "<div onclick='select(".json_encode($buffer).")'>";
Try to change line:
echo "<div onclick='select(\" ".$buffer." \");'>".$buffer."</div><br/>";
to
echo "<div onclick='select(\" ".rtrim($buffer)." \");'>".$buffer."</div><br/>";
or to:
echo "<div onclick='select($(this).text());'>".$buffer."</div><br/>";
I'm trying to get php code out of a HTML template file to execute it and place the result back.
What regular expression code can I use? And is there a method that also return the position of the found first tag?
<p>some html</p>
<?php $some = "php code"; ?>
<p>some <em>more</em> html</p>
<?php $some = "more php code"; ?>
I want the php code filtered from the html.
preg_match("/<\?.*?\?>/m",$output,$matches)
or
preg_match("/<\?.*?\?>/s",$output,$matches)
Should match all lines.
Instead of "getting the PHP out and putting it back" you should pass the variables to the template file.
Something like this:
<?php
function loadTemplate($path,$data=array()){
if (file_exists($path) === false){
throw new Exception('Template not found:'.$path);
return false;
}
extract($data);
ob_start();
require($path);
$return = ob_get_contents();
ob_end_clean();
return $return;
}
$vars = array('var1'=>$value,
'var2'=>$somevalue,
'var3'=>$someothervalue,
'var4'=>$blab);
$template = loadTemplate('path/to/thefile.php',$vars);
?>
Then access the $vars array values from within thefile.php like
echo $var1
echo $var2
ect
Hope it helps
