PHP - Can't Wrap My Brain Around This One
I am trying to create some navigation link with sublinks in a <ul> list. Here is the set up.
Table = categories fields: id cattitle = title parentid = level of the link (0 = top level) cat_loc = the id value of the link that this link will be sublink of example: 1st link: id 1, title - home, parentid - 0, cat_loc - null; 2nd link: id - 5, title - info, parentid - 0, cat_loc - null; 3rd link: id - 6, title - test, parentid - 1, cat_loc - 5; so test should be a sublink of info. Here is what I have for code so far... <?php include $_SERVER['DOCUMENT_ROOT'] . './includes/magicquotes.inc.php'; include $_SERVER['DOCUMENT_ROOT'] . './includes/db.inc.php'; $result = mysqli_query($link, 'SELECT * From categories order by orderby asc'); if (!$result) { $error = 'Error getting categories: ' . mysqli_error($link); include 'error.php'; exit(); } while ($row = mysqli_fetch_array($result)) { $navlink[] = array('id' => $row['id'], 'cattitle' => $row['cattitle'], 'cat_loc' => $row['cat_loc'], 'parentid' => $row['parentid']); } echo '<ul>'; $count = 0; foreach ($navlink as $nav): { if ($nav['parentid'] == 0) { if ($count!=0){echo " | ";} echo '<li>' . '<a href="home.php?id=' . $nav['id'] . '"' . ' ' . 'title="' . $nav['cattitle'] . '">' . htmlspecialchars($nav['cattitle']) . '</a>'; $count++; } if ($nav['parentid'] != 0) { $result2 = mysqli_query($link, 'Select * From categories where "$nav[cat_loc]" = "$nav[id]"'); if (!$result2) { $error = 'Error getting categories: ' . mysqli_error($link); include 'error.php'; exit(); } echo '<ul>'; while ($row2 = mysqli_fetch_array($result2)) { $subnavlink[] = array('id' => $row2['id'], 'cattitle' => $row2['cattitle']); } foreach ($subnavlink as $subnav): { echo '<li>' . '<a href="home.php?id=' . $subnav['id'] . '"' . ' ' . 'title="' . $subnav['cattitle'] . '">' . htmlspecialchars($subnav['cattitle']) . '</a></li>'; } endforeach; } } endforeach; echo '</ul>'; yes I do have the php closed further down the page. Part of my problem is that the sublinks won't be in the database right after their parent links so I don't think the way I have my foreach loop set up is right. I know I don't have my <ul>'s and <li>'s closed correctly yet. I just want to get the subnavs to show up, I can fix those later. Any ideas? Similar TutorialsI think this problem requires LOTS of brainpower, and as I am absolutely convinced at this point that I have none, I was kind of hoping someone could steer me in the right direction at the very least. What I'm scripting right now is a search form that allows users to browse members based on what they type in the forms. There's about 8-10 forms of various criteria, such as age, country, birthdate, email, etc. And once they hit submit, all the information they typed gets sent to the url ($_GET, in other words). Now, the way I structured my script is like this: Code: [Select] <?php //If nothing was submitted (or if the url is completely blank) if ($_GET == array ()) { //Define a variable that will be used to query the members; in this case, it would select all members $query = "SELECT * FROM fans"; } else { //If the user typed at least one thing (in the form OR the url) if (count ($_GET) == 1) { //If what they typed is only for one criteria, define a variable that creates a query for only ONE criteria to search for $query = "SELECT * FROM fans WHERE"; foreach ($_GET as $field => $value) { $query .= " $field = '$value'"; } //If the user has typed in more than one field and hits search } else { //Define a variable for a query that selects members based off each criteria $query = "SELECT * FROM fans WHERE"; foreach ($_GET as $field => $value) { $query .= " $field LIKE '%$value%' AND"; } } } ?> Now, the problem with the above script is the very last part...defining a query to run if more than one field is selected. Because I'm using a foreach loop to structure that query, my options seem rather limited with what I can and can't do as far as querying the database. And the problem lies in where it says "$field LIKE '%$value%' AND". Because of the way the script is set up, the last $_GET variable will have "AND" at the very end, and when it runs through the mysql_query() function, it breaks, and does NOT work. Is there a way around this? I figure it probably requires some complex mathematical equation (one which I have absolutely no idea on how to create). Can anyone help? For some reason I cannot think today. Code: [Select] <?php class { function meh() { $blah = $this->profile(); echo $blah->weirdname; } function profile() { // this is where I'm stuck.. // how do I properly set weirdname? } } ?> It's been a while since I've played with classes (been doing other things) so how do I set up the function profile() to return a value for weirdname. It's one of those days after a long weekend and a rainy morning. Simply trying to get the correct message depending on the variable's value
if($a = 'one'){
echo "POOR";}
if($a = 'two'){
echo "GOOD";}
if($a = 'three'){
echo "VERY GOOD";}
if($a = 'four'){
echo "EXCELLENT";}
Not sure if I need to use ==, extra quotes, or ELSEIF for the best result.
Okay, I have a 3 column table layout on my forum, I want users to beable to select where they want 1 of there profile sections to go under, (and display order) either, left middle or Right side. See now I can code the javascript/etc ajax to make them update if selected to move to (any direction) But I need help to do it server side, what kind of value/row in my db should i use? just 1 field and use arrays? Also, let's say I want to move the "Calendar" to the middle or far right, and save that position, what kind of functions would i be working with (in php) I can prob do it if I use like 200 IF and ELSE conditions, but that would take way to long, any help? I've been trying to wrap my head around this for about two hours now. The file uploads just fine, the entry goes into the database just fine, EXCEPT for the file name like it's supposed to do. I wrote the code from scratch... it worked fine, then it broke (that's the way it's supposed to work, right?) Anyways, if anyone could take a look-see and point out what I'm missing? I've tried throwing errors on all the queries, I've made sure the filename is passed from the upload form, the form does have the proper enctype. require 'dbconfig.php'; $title = escape($_POST['title']); $content= escape($_POST['content']); $time = time(); //Check the file. if (!empty($_FILES['attachment'])) { //$filename = the name as saved on user's the computer. //$filename = $_FILES['attachment']['name']; if($_FILES['attachment']['type'] === 'image/jpeg' || $_FILES['attachment']['type'] === 'image/jpg' || $_FILES['attachment']['type'] === 'application/pdf') { //Move the file only if it's uploaded. if (is_uploaded_file($_FILES['attachment']['tmp_name'])) { //Whoops, an error. if (!move_uploaded_file($_FILES['attachment']['tmp_name'], './attachments/' . $_FILES['attachment']['name'])) { die('Error: File not uploaded. Please make sure it is a JPEG image or a PDF document.'); } else { $filename = $_FILES['attachment']['name']; } } } } if( $filename = '' || empty($_FILES['attachment'] )) { die('No attachment found. Please <a href="javascript: history.go(-1)">Go back</a>'); } if ($title === '') { die('News title is empty. Please <a href="javascript: history.go(-1)">Go back</a>'); } if ($content === '') { die('News content is empty. Please <a href="javascript: history.go(-1)">Go back</a>'); } else { if (mysql_query("INSERT INTO news (news_title, news_content, news_posted, news_edited, news_attach_path) VALUES ('$title', '$content', '$time', '0', '$filename')") or die(mysql_error())) { $posted = true; } else { $posted = false; } } ?> Help. I used the great Simple SQL search tutorial provided by this site, but when I tried to customize it for my site, it keeps falling apart. I am a newbie, but any disgust at my idiocy is fine as long as I find a ball of string to lead me out of the labyrinth.

It wont go past the check fields are filled in validation. Can anyone spot what I'm doing wrong?

My brain has completely froze and I can't figure out how to do this. I have one date, that is somewhat static it doesn't change regularly but it changes. Anyway let's say this timestamp is: 2011-07-12 10:30:00 and the current timestamp is 2011-07-13 10:30:00 That's exactly a day difference, which will produce 86400 seconds. How would I write this in PHP? Hi all, for some reason I cant see this blantantly obvious query. I have 3 rows in my database, all with an id of 1, their is a column called price which contains three different float values, how the hell do I write a query in php for this?! Code: [Select] $q = mysql_query("SELECT price FROM mytable WHERE id=1") ????Thanks! Howdy, I'm in trouble here. Does someone know how to wrap a url which is in the string with href tag without writing like a few hundred line long code? Example: Befo "This is a url http://www.domain.com and then some text" After: "This is a url <a href="http://www.domain.com">http://www.domain.com</a> and then some text" the string is to be received by a flash application right after.

http://www.des-otoole.co.uk/se2/WoodFuel.phpHi in this page AT THE BOTTOM I have a large div float left. A smaller inner div float right. ( this has to inner divs with pictures) I want the text in the outer div to wrap the float right div Any help please. Code: [Select] 30|24|17,5|4|20,15|13|33,15|22|33,9|20|22 Let's say my output is that, Realistically every 3numbers is 1 Ticket they are seperated by a "," (comma) I want to wrap parenthesis around them so the output would look like this Code: [Select] (30|24|17) (5|4|20) (15|13|33) (15|22|33) (9|20|22) Now would I have to use regex.. or not cuz regex is extremely difficult Thanks I have this javascript code that loads in the footer. I only need this javascript to load on a static home page, not on all other pages.

So far I have this php statement, but I'm having trouble wrapping it in this php code.
<?php if ($page=="home") echo " "; ?>I'm not sure if putting the whole javascript code above is a good idea in the echo quotes. Is there an easier or better way of wrapping javascript in PHP? Your help appreciated. I need to wrab <b> tags around the current Letter (If they clicked on it) Code: [Select] $letters = range('A', 'Z'); $menu=(empty($menu))?'':$menu; $menu.='<center><div class=pages>Starts With: '; foreach ($letters as $letter) { $menu .= '<a href="?a=(^_-)&muffin='. $letter .'">'. $letter .'</a>'." • "; } $menu.= '</div></center>'; if ( isset( $_GET['muffin'] ) AND in_array($_GET['muffin'], $letters ) ){ // CONNECT TO DATABASE AND QUERY $q_extra .= " AND m.name LIKE '".mysql_escape_string($_GET['muffin'])."%'"; // DO QUERY AND CHURN OUT RESULTS } I tried Code: [Select] if ($_GET['muffin'] == $letter){ $boldtag1 = '<b>'; $boldtag2= '</b>'; } I tried that inside my foreach and it's not working, it shows the bold stuff all over, not around the current selection ? Anyone can chime on this one for me? ty Current selection I mean around the '.$letter.' so it looks nice and bolded if clicked on Hello all 1st post here I red in an older post how to add <br /> using the wordwrap() function , ok i used it it worked , but not as i was expecting and here is the point i need your help. I have a table which i pull some strings from the database.Horizontal space is limited to i wanted arround 70 charecters per line. The problem i have is because i used the above function the text ofcourse always keeps 70 characters and makes the text formation not to look so appealing..here is what i mean as an example Pros: bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla bla This is how the output is looks like in the page. I would like something like this : Pros: bla bla bla bla bla bla bla bla bla bla bla blabla blabla bla bla bla bla bla blabla blabla blabla blabla blabla blabla blabla blabla blabla blabla bla bla blabla blabla blabla blabla blabla blabla blabla blabla blabla blabla bla If there is a way to tell php : hey make the 1st line to have 70 characters and all the rest to have 90. Is a visual problem in other words. The code is this Pros: <?php echo wordwrap(($row_site_list['pros']),70,"<br />",true)?><br /> Any ideas, pointers? Thanks got this function in php.net i guess function mywordwrap($string) { $length = strlen($string); for ($i=0; $i<=$length; $i=$i+1) { $char = substr($string, $i, 1); if ($char == "<") $skip=1; elseif ($char == ">") $skip=0; elseif ($char == " ") $wrap=0; if ($skip==0) $wrap=$wrap+1; $returnvar = $returnvar . $char; if ($wrap>8) // alter this number to set the maximum word length { $returnvar = $returnvar . "<wbr>"; $wrap=0; } } return $returnvar; } after using this when i try to validate my page in http://validator.w3.org i get this error Line 124, Column 38: end tag for "wbr" omitted, but OMITTAG NO was specified <td width="15%">sdfasdfsdfadfddfdfsafasd<wbr>a</td> ✉ You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">". what is the fix for this? I have made a classified website. it works and I am proud of it. But as far as securing it goes, I have done almost nothing and I am sure, if in case the site becomes popular, it would be compromised with ease. So I have started reading a book ' essential php security' and am reading several articles on php security online , but am still unable to wrap my head around the whole security issue. Can someone help me ? there are a lot of unfamiliar topics, filtering, escaping , validating, session hijacking etc etc and it all goes over my head. Its a classified website , considering this on what should I concentrate on as far as security goes ? btw what I have managed to do is use mysql_real_escape_string on every var going into a mysql $query. Thanks |
