I am working on a project for school, so needless to say I am a beginner at all of this. I am having trouble passing my form data to my XML file. I am receiving a
Fatal error: Call to a member function writeXML() on a non-object from save-xml.php line 53
which points to my define-classes.php. I have defined the ticket class in the define-classes file. I am writing just a help ticket site where users can input and view tickets. below is the code.
<?php

And the XML File
<tickets.xml>
</tickets.xml>
Talk about re-inventing the wheel, I tried using the above code as most of it was provided by my instructor for us to incorporate, however, I found that all this was for not as three simple php commands allowed to me to append into my XML no problem. I ended up using a mixture of CreateElement(), appendChild(), and createAttribute(). Thank you for the looking at this with me though guys.

I have just started to learn PHP, and started it with VS Code
But unfortunately when trying to create a new simple 'data.txt' file, but without any luck. here is the code
<?php

Every time i reload the server it does not create any new '.txt' file, even when i try with different values i am not able to create.enter code herenter code heree
I looked up to find different information, i have tried to change the permissions to -- 755 -- 'Path' ==>> /var/www/html.
The same goes to debugging, i have tried but no errors are displaying, assuming it is some small thing i tried to look into the code 100 times but with no result.
Thanks in Advance.
There's no condition where $error could be false (you initialize it to true and only set it to true), so you can never enter the if(!$error){ block.
You'll probably want to change that initial
$error = true;
to
$error = false;
I just can't figure this out, I keep getting Unable To Create Group.
What I'm attempting to do is you submit a forum, and it creates a file with some info in it. If the group name already exist(the file) then tell them that. Though I keep getting as I stated "Unable To Create Group" as my die message.
This is the PHP part:
<?php
if($_POST['ownername'] && $_POST['groupname']){
$ownername = htmlspecialchars($_POST["ownername"]);
$groupname = htmlspecialchars($_POST["groupname"]);
echo 'Owner is ' . $ownername . ' and the group is ' . $groupname;
$groupfile = '/groups/' . $groupname . '.txt';
if(file_exists($groupfile) == false){
$newgroup = fopen($groupfile, 'w') or die("Unable to create group");
$txt = "Users:" . $ownername;
fwrite($newgroup, $txt);
fclose($myfile);
echo "<font style='color:green'>The group has been created! You may access it <a href='chat.php?group=" . $groupname . "'>here</a></font>";
} else {
echo "<font style='color:red'>The group name is taken, please use another name or wait for it to be released</font>";
}
}
?>
Then this is my HTML part:
<form action=<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?> method="post">
<input type="text" name="ownername" placeholder="Username"/>
<input type="text" name="groupname" placeholder="Group Name"/>
<input type="submit" value="Create"/>
</form>
Any and all help is appreciated, thank you very much!
If the filename doesn't exist yet, use 'x' instead of 'w' to create a file and allow writing into.
$newgroup = fopen($groupfile, 'x');
I have made an attempt to write a PHP code that takes the contents of an HTML form then write them into a file. I have that down just fine, but I have another problem. I want to take an input of a field in the form and make it the file name that I am writing to.
Here is my PHP code:
<?php
if(isset($_POST['forwhom']) && isset($_POST['importance']) && isset($_POST['message'])) {
$file = "students.html";
$data = nl2br('-' . $_POST['forwhom'] . ':' . ' ' . $_POST['message'] . ' ' . $_POST['importance'] . "\n");
$ret = file_put_contents($file, $data, FILE_APPEND | LOCK_EX);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo "Success! Student added to database.";
}
}
else {
die('no post data to process');
}
?>
Currently, I am writing to the file "students.html" However, I want to write to the file "Dad.html", which happens to be the input in the field by the name of forwhom.
Basically, I am asking this: What do I use to replace "students.html" (line 3) so that the file name will be the same as the input of the field forwhom?
I apologize if that didn't make any sense. Thank you very much!
First check if data has been posted on your form using $_SERVER['REQUEST_METHOD'] == "POST".
For simplicity sake save all your "POST" requests in a variable eg.
$file = $_POST['forwhom'];
$importance = $_POST['importance'];
$message = $_POST['message'];
I sometimes find it much easier using empty() instead of isset().
Create a variable, lets say $status which would store all your messages, then any where in your HTML section you just use the $status to display the appropriate message to the user. Check below how i make use of $status in the form.
By doing so is much cleaner and makes your code more dynamic in a sense.
<?php
if ($_SERVER['REQUEST_METHOD'] == "POST") {
$file = $_POST['forwhom'];
$importance = $_POST['importance'];
$message = $_POST['message'];
if (!empty($file) && !empty($importance) && !empty($message)) {
$data = nl2br('-' . $file . ':' . ' ' . $message . ' ' . $importance . "\n");
$file .= ".html";
$ret = file_put_contents($file, $data, FILE_APPEND | LOCK_EX);
if ($ret == true) {
$status = "Success! Student added to database.";
} else {
$status = "Error writing to file!";
}
} else {
$status = "Please enter name, email and message";
}
}
?>

I added a form just for explanation sake, hope it helps.
i have this code to get the search resutls from the api:
querygoogle.php:
<?php
session_start();
// Here's the Google AJAX Search API url for curl. It uses Google Search's site:www.yourdomain.com syntax to search in a specific site. I used $_SERVER['HTTP_HOST'] to find my domain automatically. Change $_POST['searchquery'] to your posted search query
$url = 'http://ajax.googleapis.com/ajax/services/search/web?rsz=large&v=1.0&start=20&q=' . urlencode('' . $_POST['searchquery']);
// use fopen and fread to pull Google's search results
$handle = fopen($url, 'rb');
$body = '';
while (!feof($handle)) {
$body .= fread($handle, 8192);
}
fclose($handle);
// now $body is the JSON encoded results. We need to decode them.
$json = json_decode($body);
// now $json is an object of Google's search results and we need to iterate through it.
foreach($json->responseData->results as $searchresult)
{
if($searchresult->GsearchResultClass == 'GwebSearch')
{
$formattedresults .= '
<div class="searchresult">
<h3>' . $searchresult->titleNoFormatting . '</h3>
<p class="resultdesc">' . $searchresult->content . '</p>
<p class="resulturl">' . $searchresult->visibleUrl . '</p>
</div>';
}
}
$_SESSION['googleresults'] = $formattedresults;
header('Location: ' . $_SERVER['HTTP_REFERER']);
exit;
?>
search.php
<?php
session_start();
?>
<form method="post" action="querygoogle.php">
<label for="searchquery"><span class="caption">Search this site</span> <input type="text" size="20" maxlength="255" title="Enter your keywords and click the search button" name="searchquery" /></label> <input type="submit" value="Search" />
</form>
<?php
if(!empty($_SESSION['googleresults']))
{
echo $_SESSION['googleresults'];
unset($_SESSION['googleresults']);
}
?>
but with this code, I cant add a searchstring..
how can i add a search string like search.php?search=keyword ?
thanks
ok, have it! changed into this code:
querygoogle.php
$_SESSION['googleresults'] = $formattedresults;
header("Location: search.php?searchquery=" . $_GET['searchquery']);
exit;
... &start=20&q=' . urlencode('' . $_GET['searchquery']);
search.php
<form method="get" action="querygoogle.php">
I want to Remove the Sessions from this php code, actually if someone searches i get this url search.php?searchquery=test but if I reload the page, the results are cleaned. how can I remove the Sessions to get the Results still, if someone reloads the page? this are the codes:
search.php
<?php
session_start();
?>
<form method="get" action="querygoogle.php">
<label for="searchquery"><span class="caption">Search this site</span> <input type="text" size="20" maxlength="255" title="Enter your keywords and click the search button" name="searchquery" /></label> <input type="submit" value="Search" />
</form>
<?php
if(!empty($_SESSION['googleresults']))
{
echo $_SESSION['googleresults'];
unset($_SESSION['googleresults']);
}
?>
querygoogle.php
<?php
session_start();
$url = 'http://www.example.com';
$handle = fopen($url, 'rb');
$body = '';
while (!feof($handle)) {
$body .= fread($handle, 8192);
}
fclose($handle);
$json = json_decode($body);
foreach($json->responseData->results as $searchresult)
{
if($searchresult->GsearchResultClass == 'GwebSearch')
{
$formattedresults .= '
<div class="searchresult">
<h3>' . $searchresult->titleNoFormatting . '</h3>
<p class="resultdesc">' . $searchresult->content . '</p>
<p class="resulturl">' . $searchresult->visibleUrl . '</p>
</div>';
}
}
$_SESSION['googleresults'] = $formattedresults;
header("Location: search.php?searchquery=" . $_GET['searchquery']);
exit;
?>
thank you for your help!!
This is against google's terms of use. Use google API
