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/>";

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>
how to read a php file and echo it in a html file?
i try to use readfile() , file() file_get_content() to read a php file.
but when i echo file_string its parsed and then show.
how i can prevent to pars stirng var that included php codes.
here my code:
<?php
$path = '..../ex.php';
$source = fopen($path , "r");
echo fread($source,filesize($path ));
fclose($source);
?>
how to echo $source without compiled or parsed.
With this function
<?php
echo htmlspecialchars($text);
?>
php.net/htmlspecialchars
fread should works fine. Remember that when you use echo it prints <?php opening tag and in rendered page it can be not visible.
To test it, just try with var_dump:
$content = fread($source,filesize($path));
var_dump($content);
I'll go out on a limb and guess that the code is not showing up completely in your HTML page, because the browser is trying to interpret <?php as HTML tags. The solution is to HTML encode any text which may contain characters with a special meaning in HTML:
echo htmlspecialchars(file_get_contents('..../ex.php'));
See The Great Escapism (Or: What You Need To Know To Work With Text Within Text).
use this
$path = 'ex.php';
$source = fopen($path , "r");
echo "<textarea style='border:0px; overflow: hidden; width:100%; height:100% '>";
echo fread($source,filesize($path ));
echo "</textarea>";
fclose($source);
So right now, I have a simple function that I use to call some text content:
function htmlstuff() { ?>
<p>html text content here</p>
<? }
And on a page I call the text using:
<?php htmlstuff() ?>
Now, I need to figure out how to use "search and replace" for whatever text is in the function. I've tried things like
function str_replace($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 am building a site that parses a spanish dictionary. If you look up the word HOLA, you will receive the definition, but for other words, you get suggestions, like CASA: http://verbum.xtrweb.com/verbumpost.php?word0=hola&word-1=casa
I wish to: when you click on the suggestions (like CASAR in the example I posted above) to print the result in a div like HOLA. Here is the code I am currently using:
$words = array('word0','word-1');
function url_decode($string){
return urldecode(utf8_decode($string));
}
$baseUrl = 'http://lema.rae.es/drae/srv/search?val=';
$cssReplace = <<<EOT
<style type="text/css">
// I changed the style
</style>
</head>
EOT;
$resultIndex = 0;
foreach($words as $word) {
if(!isset($_REQUEST[$word]))
continue;
$contents = file_get_contents($baseUrl . urldecode(utf8_decode($_REQUEST[$word])));
$contents = str_replace('</head>', $cssReplace, $contents);
$contents = preg_replace('/(search?[\d\w]+)/','http://lema.rae.es/drae/srv/search', $contents);
echo "<div style='
//style
", (++$resultIndex) ,"'>", $contents,
"</div>";
}
I am starting to code, so please be patient, I have also tried with some DOM code a friend suggested but it failed to function.
i think you need to put an iframe inside div.
or try to make the click f'n happen in javascript/jquery - make some ajax call, upon click, and show/append the returned results (suggestions) inside the div
I checked php.net and read a few examples of how urlencode( ) works but somehow I just can't get it right. Can someone give me a hand?
it'll be a lot to example so hopefully my brief example would make sense.
I have a page called 2.php and it was called to show some contents of a .txt file choosen in 1.php.
I am told to make a link for 3.php and the link should look something like /3?filename=a.txt
with filename as GET parameter name and Ensure GET parameter value is urlencoded using the urlencode( ) function.
but I'm confused how and where I should put urlencode() to make it work.
I'll paste my 2.php code here...I simplified the codes a bit...
<?php
$fileContents = file("./aaa/" . $_GET["course"] . ".txt");
echo "<table border=\"1\">";
foreach($fileContents as $row)
{
echo "<tr>";
$contents = preg_split("/,/", $row);
foreach($contents as $eachline)
{
echo "<td>";
if(!(preg_match("/#/", $eachline)))
{
echo trim(ucfirst($eachline));
}
else
{
echo trim(strtolower($eachline));
}
echo "</td>";
}
echo "</tr>";
}
echo "</table>";
echo "<a href='./1.php'>Choose another txt file</a><br/>";
echo "or<br/>";
echo "<a href='.3.php?'>Work with this txt file</a>";
?>
BUT…the 3.php option must have a query string appended to it: the name of the text file that was selected in 1, so instead of ./3.php, the url should be something such as ./3?filename=asdf.txt
Use “filename” as the GET parameter name. Ensure the GET parameter value is urlencoded using the urlencode( ) function.
but I'm just not sure how to get it to work....
You can wrap the part that should be url encoded in the function within the string:
$url = 'http://www.google.com?q=' . urlencode($search);
OR in html
http://www.google.com?q=<?php echo urlencode($search); ?>
Where . is the concatenation of 2 outputs.
