PHP - Turning Html Into If Else

I recently had a need to check several arrays, and if an index wasn't set, set a variable to a given value.  The code was such that I couldn't perform the isset check all at once.  I then thought "wouldn't it be great if I could try the script, and catch the error or warning". Searching a bit, I came across the following script.  I am a little nervous, however, that there might be negative consequences of doing so.  Thoughts?

set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
// error was suppressed with the @-operator
if (0 === error_reporting()) {
return false;
}

throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});

try {
dns_get_record();
} catch (ErrorException $e) {
// ...
}

Hi, I'm pretty new to PHP, struggled my way through most of my encounters with PHP so far, but getting the hang of it 

I'm looking for a simple script that turns a number or word served by a weather station into a graphic. E.g. If the temp is 20 degrees, a graphic I've designed would be shown, or a cloud or the sun or whatever.

At the moment the weather station feed is converted from 'webtags' in to php tags (temp is $temp, wind is $wind etc.) and these echo out as numbers and words on the website.

I can sort of see how it would work in my head, but need a little help.

Can anyone please point me in the right direction?

Thanks

I got a tab menu, where the user choose his category and a list of sub categories appear. Personally I like the old fashion way, where everything listed like in craiglist.com ...
How can I turn the following tab menu, into a simple 3 column list?

<!--CATEGORIES-->
  <div id="selCategories">
    <div class="slidetabsmenu menu_fix">
      <ul>
        <?php

         if(isset($groups) and $groups->num_rows()>0)


         {

         $i=0;

         foreach($groups->result() as $group)

         {
                  ?>
        <li id="gr<?php echo $i;?>" class="<?php if($i == '0') echo "selected"; ?>"><a href="javascript:;" onclick="getCat('<?php echo $i ?>','<?php echo $groups->num_rows ?>',<?php echo $group->id;?>);"><span><?php echo $group->group_name;?></span></a></li>
        <?php $i++;}

         }

Your tips, directions, and support is highly appreciated.

right now i have my date system to say "X amount of seconds ago, X hours ago, X days ago, X years ago, How could i turn mktime()   (1290874161)
into a mm/dd/yyyy format? so it would say like, "Nov 27, 2010 at Hour:Minute"  (whatever the hour/minute is)

I have got a date field in my mysql database with events, and as you know date in MYSQL uses yyyy/mm/dd but I would first like to turn this around to dd/mm/yyyy but also turn this into for example "Tuesday - May 1990" would anyone like to point me into the right direction?

Much appreciated!

 
Hi guys,
I have written a page that contains a form.  When the user chooses a color, it is posted, then the posted value is re-written as a filename, sent through a function, and the image on the page uses the "colorized.gif" created by the function to make an image swap "onclick.  Problem is, no matter the choice, it always changes the picture to orange! Here is the code for the form:

<?php include('function.php'); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>PHP GD CONFIGURATOR</title>
</head>

<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
Red<input type="radio" name="color" value="red" />
Orange<input type="radio" name="color" value="orange" />
Ivory<input type="radio" name="color" value="ivory" />
Black<input type="radio" name="color" value="black" />
<input type="submit" name="submit" value="submit" />
</form>
<?php if($_POST['color'] != NULL){
echo $_POST['color']; 
$file =('gdimages/' . $_POST['color'] . '.gif');
createImg($file);
}
?>

<img src="default.jpg" name="lola" alt="lola dining chair" onclick="this.src = 'colorized.gif'" />
</body>
</html>

And here is the function...


function createImg ($imgname1)
{
$base = imagecreatefromgif("gdimages/base.gif");
$top = imagecreatefromgif($imgname1);

   if ($top) { 
       imagecopy($base, $top, 0, 0, 0, 0, 250, 250);
   imagejpeg($base, 'colorized.gif');
       imagedestroy($base);
   }
   else{
header("Content-Type: text/html");
}
   
}


I really can't understand it...this is my first attempt at programming something new by myself...and I really need it to work!!! I also plan for this to work with combining more than 2 images from more than two choice menus...so debugging now is definitely necessary. Any suggestions?

i run several wordpress on domains - and wthin the wordpress i have a plugin that allows uploads of images -within a certain plugin

the interesting thing: image upload is - sometimes possible and sometinmes impossible:

see here the circumstances -

PHP Version : 5.3.28
PHP Safe Mode : On

image upload is impossible -

and on the same server - a second vhost

PHP Version : 5.3.28
PHP Safe Mode : off

image upload is possible

why is this so - does it have to do with the safe-mode -

I have a form that users input user name, password, and email... all writes to csv fine.  My problem is I need to concatenate a a string with a variable and some html code will preserving the html when written to the csv..

I need the csv to be this

username,password,email,user,category,text with http://sub.domain..com/splash/,something,something

here's what i have

Code: [Select]
<?php
if($_POST['formSubmit'] == "Submit")

$varUserName = $_POST['username'];
$varPW = $_POST['PW'];
$varEmail = $_POST['email'];
{
$fs = fopen("testcsv.csv","a");
fputcsv($fs, array($varUserName,$varPW,$varEmail,"user","title",",category","some text '<a href="http://$varUserName.url.com/splash/>site.com</a>',));
fclose($fs);

exit;
}
?>
and of course I'm getting

Parse error: syntax error, unexpected T_STRING, expecting ')' on line 9

Hey guys,

I'm a total newbie here, and just about as a new to php. 

My issue:
I have a very large .html file that contain multiple articles (I actually have a few of these, but we'll start with one for practicality).  The article titles are all wrapped in <h2> tags, there are 10 articles in one file.  The articles are very simple, just a title wrapped with <h2> and then a few paragraphs wrapped in <p> tags. 

What I want to know how to do:
I want to know if there's a way to open that file, and have each article saved as it's own .html or .txt document (the title & following paragraphs of each article).
Ultimately taking my 1 large file, and creating the subsequent 10 smaller files from the articles inside of it.

I am having trouble explaining this in text so I'll try to illustrate:
I have "Articles.html" - which contains (article1,article2,article3.. ..article10)
I want to split "Articles.html" and create "Article1.html", "Article2.html", "Article3.html", etc.

Is that possible?  Or am I looking at something far more complex than I can imagine at this point - perhaps something I'd be better off doing by hand?




Ultimately I intend to stick all these articles into a database, but that's the 2nd part of what I want to do (and I think will be the easier of the tasks).
Let me know if you need any additional information in the event my description above is unclear... I simply am having issues figuring out how to separate out the text into individual articles.

Hi,

How do I open all HTML file contained in a folder, then search for the title of the page, and save the title in the database?
Also, is it possible to do this using functions?

Cheers.

require_once 'phpSimpleHtmlDomClass.php'; $html = '<div> <div class="man">Name: madac</div> <div class="man">Age: 18 <div class="man">Class: 12</div> </div>' $name=$html->find('div[class="man"]', 0)->innertext; $age=$html->find('div[class="man"]', 1)->innertext; $cls=$html->find('div[class="man"]', 2)->innertext;

wanna get a text from each div class="man" but it didn't work because there is a missing closing div tag on 2nd line of html code. please help me to fix this.

thanks in advance.

I'm trying to submit html/php code through an html form and then insert it into a mysql database. I've got the following code so far (without the insert into database query), however when I submit the form I get pushed through to my 403 page. If i comment out the textarea that contains the code I am trying to submit, then it goes through fine.

Any ideas?

Hi Everybody.

I hope someone here can advise the correct method for storing html/text in a MySQL DB AND retrieving it for updating via a <textarea>

Basically, I need to store in my DB knowlege base articles, which have a title, category, product version/edition, description, solution, notes, etc... standard KB fields.. sorta...

The issue I am experiencing, or the trouble I am having, is when I need to store both formatting HTML and output HTML in the solution or notes fields, html special chars are being interpreted and the HTML that should be displayed is not there. The char codes are interpreted and the browser then "hides" the HTML tags.

For example, the solution may be this:

Code: [Select]
Find the following line:

&lt;serverURL&gt;URL&lt;/serverURL&gt;

Change the URL to reflect your current server URL.

The html chars are interpreted and changed to the actual less than and greater than signs rather than their &...; form (ie: &lt; &gt; &nbsp etc.)

Some code snippets if it helps...

Creating a record:

Code: [Select]
...
$sol = addslashes($_POST['asol']);
$notes = addslashes($_POST['anotes']);
include('./conf/connect.php');
mysql_query("INSERT INTO `faq_kb`.`articles` (`id`, `solution`, `notes`, `updated`) VALUES (NULL, '$sol', '$notes', NULL) ") or die(mysql_error());
mysql_close($conn);
...

Retrieving a record:

Code: [Select]
...
include('./connect.php');
$get = $_GET['a'];
$sql = "SELECT * FROM articles WHERE id='$get'";
$result = mysql_query($sql);
mysql_close($conn);
while($row=mysql_fetch_array($result))
{
$solution = $row['solution'];
$notes = $row['notes'];
}
...
<h4>Solution:</h4>
<div align="right"><textarea name="rsol" style="width:550px;height:150px;">
<?php echo $solution; ?>
</textarea></div>
<h4>Notes:</h4>
<div align="right"><textarea name="rnotes" style="width:550px;height:150px;">
<?php echo $notes; ?>
</textarea></div>
...

Updating a record:

Code: [Select]
...
$aid = $_POST['id'];
$sol = addslashes($_POST['rsol']);
$notes = addslashes($_POST['rnotes']);
include('./conf/connect.php');
mysql_query("UPDATE `faq_kb`.`articles` SET solution='$sol', notes='$notes' WHERE id='$aid'") or die(mysql_error());
mysql_close($conn);
...

I guess, you can ignore my whole spiel above and simply answer this question:

what function do I need to use to encode the variable for inserting into the database, and what function do I then need to use to decode the variable for output so that it retains it's formatting html and my output/displayed html (&lt; &gt;)???

Thanks guys!

I hope that this makes sense...

Further Example:

This is what is output (inside the dashes):

To configure your SysAid Server logging to debug mode please do the following.

Open the file serverConf.xml located in the directory:

to

Save the change and then restart the SysAid Server service.

Notice how there are NO &lt; or &gt; chars in this?

How do I make this work


Thanks guys

Say I have the following text stored in a MySQL database...

Code: [Select]
<b>Classic Quote from movie</b>
and I retrieve it into a variable called $text, how do I properly echo that so that it keeps the bold tags and actually display the text "Classic quote from movie" in BOLD?

I'm doing something wrong somewhere along the line (simply doing "echo $text;") because it displays on the page as...

Code: [Select]
<b>Classic Quote from movie</b>

Instead of...

Classic Quote from movie

Any info on properly storing and echoing back HTML would be very appreciated.

Hi all,

I have an html form that sends formdata to a php script called example.php with the POST method.

example.php then has the following structu

Code: [Select]
<?php
if(isset($_POST['var1'])) {$var1 = $_POST['var1'];} 
else {$var1 = 'English';}
if(isset($_POST['var2'])) {$var2 = $_POST['var2'];} 
else {$var2 = 'French';}

print"
<html>
<body>
<form>
<select id='select1'>
<option>var1</option>
<option>var2</option>
<option>etc...</option>
</select>
<input type='text' id='input1'>
ETC. ETC.
</form>
</body>
</html>
";
?>
So example.php has an embedded html form. How do I specify that some elements of the form should take their values from the variables retrieved at the start of the script via the POST command?

For example, I want select1 to have 'var1' pre-selected and I want input1 to display var2. var1 & var2 get sent through to example.php fine, I just don't know how to get the embedded html form to use them.

Please help! Thanks a lot.
