PHP - Make A Variable A Certin Amount Of Chars?
I'm creating a website where writers can share stories. I have a section where the users enter a summary of there story. Anyways in the area where the story in being listed I want the the title of the story(with a link to the story) underneath the link I would like a summary. BUUUUT, the summary can get pretty long(up to 900 chars). So I am wondering if I can shorten the variable where the summary is stored, I want it to be shorten to a fixed amount of characters(maybe 200?) then followed by a ... . So how can I do this?
Similar TutorialsIf I knew what to call it I could have searched it. So I will just explain. I have a form that is pulling from a database to build the following. echo <input name='$row[id]' type='text' id='$row[id]' size=2>; This will build a page that has this <input name='22' type='text' id='22' size=2> <input name='54' type='text' id='54' size=2> This part works great. The problem is when I try to add it to the database. How can I insert variables that I don't know the names of? They will be something like $_POST[22] $_POST[54] and so on. I hope someone can understand my jibberish. I am sure there is a WAY better way to do this. Hi, I have a function where I want to sort an an array of this type: 0 = {'fruit' => 'banana', 'color' => 'yellow', 'age' => '1', 'weight' => '2', 'brand' => 'dole', 'store' => shaws'} 1 = {'fruit' => 'apple', 'color' => 'red', 'age' => '3', 'weight' => '5', 'brand' => 'fuji', 'store' => 'foodmaster'} etc etc. I then want to array_multisort this array with different parameters. One way is to sort by fruit, then color, then brand. The second way by age, then store. Code: [Select] //This is how I sort it for my first way //Let's call the array $rows function sort($rows) { foreach($rows as $key => $value) { $fruit[$key] = $value['fruit']; $color[$key] = $value['color']; $brand[$key] = $value['brand']; } array_multisort($fruit, SORT_ASC, $color, SORT_ASC, $brand, SORT_ASC $rows); } I want to try to reuse this function by passing in the keys that I want to sort with. Like doing sort($rows, array('fruit', 'color', 'brand')), then sort($rows, array('age', 'store')). Is this possible? $text = "this is a lot of effing text" what i want to do is limit it to the 10 characters so it gives back $stext = substr($text, 10); <-- this is how i thought it would work echo " $stext"; Heres what i got... function printLB1 (){ $result = mysql_query("SELECT * FROM leaderboards ORDER BY CollegeFootballPoints DESC"); while ($row = mysql_fetch_object($result)) { $leaderboard[] = $row->Username; $leaderboardPoints[] = $row->CollegeFootballPoints; } $num = mysql_num_rows($reault); //I know from here to ................... needs to be in a var or echo or something. <tr> <td>1.</td> //This will auto increment too like i++ but i cna do that myself! <td>echo $leaderboard;</td> <td>echo $leaderboardPoints;</td> </tr> //Here......................................................... } I need to pull a table row per user. But i want to somehow do it once in a function and then ill echo the function into a table after the php stuff is done. Like i want to pull every a table row per user in the function. then display the function below that way i don't have to write a whole extra query and table row per person. If you understand please help if not please let me know where i can explain more. Thanks Hello. I want to create some variables dynamically. I have this so far: for($i = 1; $i <= 4 ; $i++){ $a = 'member' . $i; $$a = array(); } Does that give me this 4 arrays?: $member1, $member2, $member3 and $member4? Of course I want some process inside of the loop, but that would depend on the variables. Would that work? thanks! Hi All, For the last post,I m very happy that i found out so many great mind who are watching my problem and solving online. anyway great thanks for all, just now i m making a project and i m facing problem in the below code "i need to know how can make this code easy or how can i make rdata variable accessible for the download button" generatecv.php file <?php if(isset($_REQUEST['submit'])) { $name=$_REQUEST['pname']; $pin=$_REQUEST['pin']; $mnumb=$_REQUEST['mnumber']; $tnumb=$_REQUEST['telenumber']; $email=$_REQUEST['email']; $obj=$_REQUEST['obj']; $title=$_REQUEST['jobt']; $activity=$_REQUEST['activity']; //$file=fopen('test.doc','a+'); //echo @fwrite($file,$name); //fclose($file); $rdata=""; $rdata.="<table id='cvtbl' border='0' align='center' > <th>Resume</th> <tr><td>".$name.":</td></tr><tr><td>Objective:</td></tr>"; $rdata.="<tr><td>".$obj."</td></tr>"; $rdata.="<tr><td>Email:".$email."</td></tr>"; $rdata.="</table>"; echo $rdata; echo "<style>#cv{display:none;}</style>"; echo "<form><input type='submit' name='dwnld' id='dwnld' value='Download'/></form>"; } if(isset($_REQUEST['dwnld'])) { header("Content-type:application/msword"); header("Content-disposition:attachment;filename=test.doc"); $fp=fopen("test.doc","r") or die("try again"); $data=fread($fp,filesize('test.doc')); fwrite($fp,$rdata); echo $data; fclose($fp); //echo $rdata."<br />".$rdata; } ?> this is the html file <html> <title>User details</title> <body> <form name='cv' id='cv' method="post" enctype="multipart/form-data" action='generatecv.php'> Enter your name<input type=text name=pname id=pname /> Zip Code<input type=text name=pin id=pin /> Mobile number<input type=text name=mnumber id=mnumber /> <br />Telephone number <input type=text name=telenumber id=telenumber /> Email address<input type=text name=email id=email /> <br />Enter your objective<br /><textarea name=obj id=obj cols=30 rows=5 ></textarea> <!--University Name <input type=text name=university id=university /> --> <br /><!--uni, city ,state ,type of degree ,full degree name,date--> <br /><!--Experience<br /><textarea name=exp id=exp cols=30 rows=5 ></textarea> --> Select type of resume <select name='type' id='type' onChange=''> <option value='0'>Graduate</option> <option value='1'>Post Graduate</option> <option value='2'>Non Graguate</option> <option value='3'>Other</option> </select> Job title<input type='text' name='jobt' id='jobt' /> <br /><!--company name,city ,state ,office number ,job description ,date of employment--> <br />Activity <input type=text name=activity id=activity size=100 /> <br />Honors/Awards<input type=text name=honor id=honor size=100 /> <input type='submit' name='submit' id='submit' value='Generate CV' /> <input type='reset' name='Reset' id='submit' value='Reset' /> </form> </body> </html> Many thanks in advance When login in (in login.php), the script is assigning user information to scalar variables like so: $user_name = $assoc['user_name']; $user_id = $assoc['user_id']; Now I'd like to make use of those variables on other pages like this for example: echo "Posted by " . $user_name; I want that to be visible for everybody, even if the user logs out. Any ideas? Hello, I'm working on a script which should read lines from a file keyword.txt create a new file with that variable name, insert the content close and loop through all the lines in the keyword file. The loop itself works but now that i'm adding the fopen fwrite and fclose i'm running into trouble. I'm not that great a coder and have pieced this together so far. I'd appreciate any suggestions on how to fix the fopen and other file functions to create unique files using the keywords from the file Thanks in advance <?php $read_file = file('keywords.txt'); foreach($read_file as $var) { $file = fopen($var, "x"); $content = "<!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>This is the title</title> </head> <body> <h2>The keyword is $var</h2> <p><p> </body> </html>"; fwrite($file, $content); fclose($file); } ?> Best method to for the following? Code: [Select] // The following $str1 and $str2 should say they are identical $str1 = "abcDEF"; $str2 = "EcFabD"; // The following $str1 and $str2 should say they are NOT identical because of the "a" "A" case difference. $str1 = "abcDEF"; $str2 = "EcFAbD"; I'm comparing bitvector strings. "ABC" is different than "abc". "abc" is the same as "cba". What's the best php function or method I should use? Thank you. Code: [Select] <?php $fspec = base64_decode($_GET['q']); if (isset($_POST['content'])) { if (!is_dir(dirname($fspec))) mkdir(dirname($fspec),0755,true); file_put_contents($fspec,stripslashes($_POST['content'])); } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Edit template</title> <style type="text/css"> body { background-color:#fff; font-family:arial,verdana; font-size:10pt; } </style> </head> <body> <div style="background-color:#fff;"> <form action="<?php echo $_SERVER["PHP_SELF"].'?q='.base64_encode($fspec); ?>" method="post"> <div><textarea id="markItUp" rows="20" cols="80" name="content"><?php include $fspec; ?></textarea></div> <div> <input type="submit" value="Save" /> <a href="javascript:window.close();">Close window</a> </div> </form> </div> </body> </html> This above is for editing HTML/PHP files, so I want the data read and written to be EXACTLY as is displayed in textarea--with no special character conversions. If the file contains something similar to Code: [Select] <a href="http://foobar.com/index.php?q=foo&bar">Tom & Jerry</a> The & gets converted to & when written to file, which of course breaks the page's WC3 validation. Is it getting converted when passed via POST? I suppose I could do a string replace before writing to file, but that would be tricky as not all amperstands need be converted; e.g., the "Tom & Jerry" above. Am I missing something obvious? Thanks in advance. I let my users to post what they would like as a text, today I noticed that I forgot disabling htlm chars, so they can even post textbox's htlm code and create a textbox in the posting section, Is there any way/function to prevent this ? Hello everyone, how i can insert to the db string that include "$_GET['id']", and i need this as is. in the table i need to see the string $_GET['id'] and not the value. any ideas ? Hi i've recently moved hosting servers as I had severe lag issues with my shared hosting. Since i've brought a dedicated linux server with apache and php. Since the move i get extra chars with the following code Code: [Select] <?PHP define( "MESSAGE", "Testing Testing 123" ); if(isset($_GET['message'])) { die(MESSAGE); } ?> My application SHOULD receive back "Testing Testing 123" like it used to with my old shared hosting. Instead now it receives the following: Code: [Select] 2f Testing Testing 123 0 And i cannot figure this out for the life of me. I'm expecting something silly to be the cause but would appreciate some guidance on this. Thanks Hi, I'm looking for a bit of help. I have a record in a MSSQL. I'm using PHP to pull that record. In the record there are the funky square characters for chr(13) and chr(10). In PHP they are totally ignored which means that the record appears on one line. I have tried replacing these with various a numerous characters but no joy. Things like Code: [Select] str_replace(' ', '<br/>', $notes); and Code: [Select] str_replace(chr(10), " ", $notes); Please help Using base64_encode to encode the name of a major function on your code and them shift the values to reach non printable chars. This way, when a newbie tries to temper your code, opening it on a editor, it will fail to run when saved! What do you think? How would I incorporate a function to simply check the "name" and "message" for a certain amount of chars, like 15 & 150? Code: [Select] <form method="post" action="chat.php"> <p><input name="name" type="text" id="name" value="your name" size="10" maxlength="15"> <input name="message" type="text" id="message" value="your message" size="20" maxlength="150"> <input name="submit" type="submit" id="submit"></p> </form> </body> </html> <?php // when the submit button is clicked if(isset($_POST['submit'])) { // strip any html tags before continuing $name=strip_tags($_POST['name']); $message=strip_tags($_POST['message']); // stop if nothing was entered if($name!='') if($message!='') { // trim any extra whitespace $data=trim($name)."\n"; $data.=trim($message)."\n"; //open the text file and enter the data $file_ar=file("db.txt"); $fp=fopen("db.txt","w"); fputs($fp,$data); if($file_ar!=NULL) { $loop=0; foreach($file_ar as $line) { // do not store more than 20 messages if($loop>=19*3) break; fputs($fp,$line); $loop++; } } fclose($fp); } } // display the messages $fp=fopen("db.txt","r"); while(!feof($fp)) { $name=trim(fgets($fp,999)); $message=trim(fgets($fp,999)); if($name!='') { echo "<p><b>$name: </b>$message</p>"; } } fclose($fp); ?> |
