  1. how do i write this in jquery? var state = document.getElementById("state"); state.options[state.options.length] = new Option();
  2. im trying to scrape the text of an image.
  3. is this possible to get the text in an image?
  4. thanks for all of your replies.
  5. i see that they use array in getting records from the database. while ( $row = @mysql_fetch_object( $this->result ) ) { $this->last_result[$num_rows] = $row; $num_rows++; } what if my records is 50,000. does array can hold that number of records, or does it use to much memory?
  6. why does wordpress is using foreach rather than while in listing records? common while ($products = mysql_fetch_object($rs) { ... } but wordpress is using foreach foreach ($posts as $post) { ... } which is better? because i'm trying to create my own code for database connection.
  7. so mysql_real_escape_string removes the quotes?
  8. i have a textarea and the content is description. how do i save this to database, because sometimes it has ' and " so it fails when i insert it into database, what should i use addslashes?
  9. what is the for writing { function myfunc { or function myfunc { it should be right after myfunc or below function myfunc?
  10. i have a form submission and it saves in my database. but sometimes i got weird characters, so when i display it on my site. the text content got weird error symbols. how do you handle those? thanks.
  11. how do you optimize this query? SELECT SUBSTR(eventDetails, INSTR(eventDetails, '|#|Name') + 8, INSTR(eventDetails, '|#|StartDate') - INSTR(eventDetails, '|#|Name') - eventTitle, SUBSTR(eventDetails, INSTR(eventDetails, '|#|City') + 8, INSTR(eventDetails, '|#|State') - INSTR(eventDetails, '|#|City') - city, IF(UNIX_TIMESTAMP(SUBSTR(eventDetails, INSTR(eventDetails, '|#|StartDate') + 13, 10)) = 0, SUBSTR(eventDetails, INSTR(eventDetails, '|#|StartDate') + 13, 10), UNIX_TIMESTAMP(SUBSTR(eventDetails, INSTR(eventDetails, '|#|StartDate') + 13, 10))) eventStartDate, IF(UNIX_TIMESTAMP(SUBSTR(eventDetails, INSTR(eventDetails, '|#|EndDate') + 11, 10)) = 0, SUBSTR(eventDetails, INSTR(eventDetails, '|#|EndDate') + 11, 10), UNIX_TIMESTAMP(SUBSTR(eventDetails, INSTR(eventDetails, '|#|EndDate') + 11, 10))) eventEndDate, SUBSTR(eventDetails, INSTR(eventDetails, '|#|State') + 9, INSTR(eventDetails, '|#|Zip') - INSTR(eventDetails, '|#|State') - 9) eventState FROM events WHERE eventDetails NOT LIKE '%Canceled:YES%' AND eventDetails NOT LIKE '%State:|#|%' AND eventDetails NOT LIKE '%Status:DELETED%' AND (eventDetails NOT LIKE '%PromoterPhone:|#|%' OR eventDetails NOT LIKE '%Link1:' OR eventDetails NOT LIKE '%UserNumber:0|#|%' OR eventDetails NOT LIKE '%UserNumber:|#|%') AND SUBSTR(eventDetails, INSTR(eventDetails, '|#|State') + 9, INSTR(eventDetails, '|#|Zip') - INSTR(eventDetails, '|#|State') - 9) = 'RI' HAVING ((eventStartDate BETWEEN '1261980000' AND '1282712400') AND (eventEndDate BETWEEN '1261980000' AND '1282712400')) ORDER BY eventStartDate ASC LIMIT 0, 20;
  12. as i said, one way. this is the thing that came up in my mind. but thanks for the another solution.
  13. <?php class cache { var $cache_dir = "cache/"; // Directory where the cache files will be stored var $cache_time = 7320; // How much time will keep the cache files in seconds var $caching = false; var $cache_file = ""; // Constructor of the class function cache() { $this->cache_file = $this->cache_dir . md5(urlencode($_SERVER["REQUEST_URI"])); if (file_exists($this->cache_file)) { //Grab the cache: $handle = fopen($this->cache_file, "r"); do { $data = fread($handle, 8192); if (strlen($data) == 0) { break; } echo $data; } while (true); fclose($handle); echo "<span style='font-size:8px;'>cache page loaded</span>"; exit(); } else { //create cache : $this->caching = true; ob_start(); } } // You should have this at the end of each page function close() { if ($this->caching) { // You were caching the contents so display them, and write the cache file $data = ob_get_clean(); echo $data; $fp = fopen(str_replace("/ww.", "/", $this->cache_file), 'w'); fwrite($fp, $data); fclose($fp); } } } ?> <html> <head> </head> <body> <?php include("cache.class.php"); ?> <?php $ch = new cache(); ?> THIS CONTENT WILL BE CACHED <?php $ch->close(); ?> </body> </html>
  14. for security you could use https and mysql_escape_string.
  15. Create two buttons on the page of the form that do separate stuff? one way is: function dothis() { document.myform.submit(); } function dothat() { document.myform.submit(); } <input type="button" onclick="dothis()" value="Do This" /> <input type="button" onclick="dothat()" value="Do That" /> it's a start, research further.
  16. or you could use image magick
  17. use this <?php header ("Content-type: image/jpeg"); /* Resize an image to 25 x 25 imgsize.php?w=25&h=25&img=path/to/image.jpg Resize an image to 50% the size imgsize.php?percent=50&img=path/to/image.jpg Resize an image to 50 pixels wide and autocompute the height imgsize.php?w=50&img=path/to/image.jpg Resize an image to 100 pixels tall and autocompute the width imgsize.php?h=100&img=path/to/image.jpg Resize to 50 pixels width OR 100 pixels tall, whichever resulting image is smaller imgsize.php?w=50&h=100&constrain=1&img=path/to/image.jpg JPEG / PNG Image Resizer Parameters (passed via URL): img = path / url of jpeg or png image file percent = if this is defined, image is resized by it's value in percent (i.e. 50 to divide by 50 percent) w = image width h = image height constrain = if this is parameter is passed and w and h are set to a size value then the size of the resulting image is constrained by whichever dimension is smaller Requires the PHP GD Extension Outputs the resulting image in JPEG Format By: Michael John G.

  18. this is what i'm looking for! thanks!
  19. how do you compute an equation inside a variable? $row['equation'] - from database. example content: ORIGINAL_PRICE - (ORIGINAL_PRICE * 0.50) example define('ORIGINAL_PRICE', 49.97); $value = $row['equation']; is it possible?
  20. the reason why my i did that code because the computation will be coming from database and i don't know how to use the computation after i get it from the database. got the idea?
  21. define('ORIGINAL_PRICE', 49.97); $computation = "ORIGINAL_PRICE - (ORIGINAL_PRICE * 0.50)"; echo (int) $computation; that code is not working but is that possible or how to code that to work?
  22. i tried unzip to extract jar files and it's working. now i could extract it to a new folder.
