I'm new in PHP so any response would be much appreciated .. thanks Hello, I am attempting to create a script where a user puts a text string into a form and clicking on submit. Then it adds that text string to a mysql database and gives the user a link back to it. Something like mysite.com/key.php?id=4 and when going to that link it will display the text string from the database but printed in an image. I wrote something up but I cannot get it to work. I may be a little in over my head. Any help is appreciated.
The way I coded this all to work is the user inputs the information into index.php which givekey.php inserts that into the database. I have not yet figure out how to do this in one single step. After that I wanted it to navigate directly to key.php which would display the key and the link to that page with the ?key=XX attribute. getkey.php <?php require_once 'dbinfo.php'; // database connection $id = $_GET['id']; // do some validation here to ensure id is safe $link = mysql_connect($servername, $username, $password); if (!$link) { die('Could not connect: ' . mysql_error()); } @mysql_select_db($database) or die( "Unable to select database"); $sql = "SELECT ukey FROM keycode WHERE id=$id"; $result = mysql_query("$sql"); $row = mysql_fetch_assoc($result); mysql_close($link); header("Content-type: image/png"); echo $row['ukey']; ?> key.php <html> <head> <title>Your Key Is Ready</title> </head> <body> <img src="getkey.php?id=1" width="175" height="200" /> </body> </html>index.php <html> <head> <title></title> </head> <body> <section id="mid_section"> <div id="boxes"> <h1> Testing input key </h1> <br/> <form id="myform" action="givekey.php" method="post"> Key:<br /> <input type="text" value="ukey"> Source:<br /> <input type="radio" value="hb">HB<br /> <input type="radio" value="ig">IG<br /> <input type="radio" value="other">Other<br /> <button id="sub">Submit</button> </form> </body> </html>givekey.php <?php include_once('dbinfo.php'); $conn = mysql_connect($servername, $username, $password); $db= mysql_select_db($database); $ukey =$_POST['ukey']; $hb =$_POST['hb']; $ig =$_POST['ig']; $other =$_POST['other']; if(mysql_query("INSERT INTO `keycode`(`ukey`) VALUES ([$ukey]); INSERT INTO `source`(`hb`,`ig`,`other`) VALUES ([$hb],[$ig],[$other]);")) ?> Edited by chrisb302, 13 November 2014 - 12:18 AM.

The 2 in the quote above is the page number. How can I extract the number between the - and the .html and replace it with another number? I've tried Code: [Select] substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long Any input would be appreciated Dear all, I would like to find the total number of individual record in MySQL with php. For example: I have different department name stored in a column in MySQL. I would like to find out the total number of each department. But I do not know the names of the department How can I do it?? Counting the total of each department without knowing their names Thanks! Hello, How can I check this string to see if it has a ~ character using php? Code: [Select] $string = 'userlocation~credentials~specialties'; Is there an easy way to find a numeric value in a string if I don't know what the string will contain? For example I want '52' out of: mystring52 Hopefully there is already a simple function to do this? I'm thinking there may not be as the string having more than one group of numbers may confuse matters. I'm just dealing with abcdef123 or similar in this case though. I am making a online Bible with search function. I was able to do the boolean search for text keywords without much trouble. Now I want a user to be able to type in an exact verse into search form and have that verse display in results. IE: User types in John 3:16 and search result displays that verse. The following works if the user types John:3:16. I cannot figure out how to do this without requiring the user to type a : after book name. Code: [Select] if($search_type=='verse'){ $query2 = explode(":", $query); $bookquery = $query2[0]; $chapterquery = $query2[1]; $versequery = $query2[2]; $result4 = $db->sql_query("select * FROM Bible$version WHERE book = '$bookquery' AND chapter= '$chapterquery' AND verse ='$versequery'"); while ($row = $db->sql_fetchrow($result4)) { $book = $row['book']; $chapter = $row['chapter']; $verse = $row['verse']; $scripture = $row['scripture']; echo "<b><a href=\"modules.php?name=Bible&call=chapter&viewbook=$book&viewchapter=$chapter&version=$version\">$book</a> $chapter:$verse</b>"; echo "<br>"; echo "$scripture"; echo "<hr>"; } if(!$query){ echo "<b>You did NOT enter any keywords.</b><br>"; } if(!$scripture){ echo "<b>No results found.</b>"; } } } Is there a function to find first integer in the string and insert a : before it? I have another question related to string searches. What I have is a string of couple thousand characters of all types but the date format is allways the same: dd-mth-year (two digits for day-three letters for month-four digits for year). Can I use the format alone to determine where the date is located which in turn would make it very easy to store that date into variables for inserting into database, etc. Is there anyway to tell php the format to look for or do I have to have actual numbers/letters to perform the search? Hi all, i have this array $str = array("apple is red", "banana is yellow", "pineaple is tropical fruit", "coconut is also tropical fruit", "grape is violet"); i want to find string "coconut" inside $str and put the whole string "coconut is also tropical fruit" into variable $coconut. can i do this? i don't want to use the this code Code: [Select] <? $coconut = $str[3]; echo "$coconut"; ?> can someone help? Thank you, Best Regards if i want find included a word in the a range how can i do it? example : Quote array("problem is an obstacle, impediment, difficulty or challenge, or any situation that invites resolution; the resolution of which is recognized as a solutionquestion raised for inquiry, consideration, or solution proposition in mathematics or physics stating something to be done"); how can i find only start 20 charecter and my found word after 20 character by end example :if my word be inquiry i want find :...soluti Quote onquestion raised for inquiryconsideration, or solution proposition... [/size] Hello, I have a few strings that contain dates along with some other text. The string looks like this: Code: [Select] Hi, could you please add these dates to the database?<br /> <br /> <br /> 2-September-2011<br /> 6-September-2011<br /> 7-September-2011<br /> 8-September-2011<br /> 9-September-2011<br /> <br /> Thank you. Dates are always the same format. Sometimes there's a single date, most times there are multiple. Does anyone know how can I get the dates from this string to add them to my sql database? Thank you! Is it pasible to find all occurrences of strings "North" and "North-East" in some txt file and save number of occurrences in some variables?? Hi
I have a MySql database and wondered if there is a code to search a table field with a given string and display the number of unique occurrences.
The table is asterisk_cdr and would like to know how many calls received daily on a perticular channel.
Thanks

Hi All, I'm new at php and I need your help. I'm trying to find a string in a website. I want my website to get a string on another website(I have full access) without really opening it on a browser. For example the string is "MyID=123456", i want to find "MyID=123456"(the MyID number is random and always changing but always 6 random numbers) on another website and output only "123456" on my website. Is this possible? Please help. Thanks Hello everyone, I am trying to select and return any rows that have a specific string in it. Let's say I have a column name "item_id" and in every row of that column I have values like so: row A: (11,22,44,34) row B: (12,56,78,98) If the user picks the number '22', I use the following SQL line to get the row in which the number '22' is contained. SELECT * FROM Persons WHERE City LIKE '%22%' and row A gets returned, just like it is suppose to. The problem is, if the user selects a single digit number like '2', both row A and row B gets returned because they both have values that contain the number '2' in it. Instance, row A has the number '22' and row B has the number '12' so both rows get returned when the number '2' is requested. I don't want that, I only want the row that has the exact number '2' or '34' or whatever number I request, to be returned. So to get around this problem, I am wrapping my numbers in letters like so: row A: (a11a,a22a,a44a,a34a) row B: (a12a,a56a,a78a,a98a,a2a) and requesting it like so: SELECT * FROM Persons WHERE City LIKE '%a22a%' My question is: Is there a better way to work out this logic? How can I test if a string has a number at the end? i.e. smith1 instead of smith? I won't know how long the string is or whether there is more than 1 number but I will know that the string's last character is a number. Thank you! |
