I've managed to insert an image in my database, but when i upload a second picture it replaces the first!What should i do?
Similar TutorialsHi. I have a script here that will let users upload an image to my website but I just can't figure out how to save the uploaded image as "upload/logo.png" so that it will replace the already existing "upload/logo.png". Help would be greatly appreciated. Code: [Select] <html> <body> <form action="" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html> <?php if(isset($_POST['submit']) && !empty($_FILES["file"]["name"])) { $timestamp = time(); $target = "upload/"; $target = $target . basename($_FILES['uploaded']['name']) ; $ok=1; $allowed_types = array("image/gif","image/jpeg","image/pjpeg","image/png","image/bmp"); $allowed_extensions = array("gif","png","jpg","bmp"); if ($_FILES['file']['size'] > 350000) { $max_size = round(350000 / 1024); echo "Your file is too large. Maximum $max_size Kb is allowed. <br>"; $ok=0; } if ($_FILES["file"]["error"] > 0) { echo "Error: " . $_FILES["file"]["error"] . "<br />"; $ok=0; } else { $path_parts = pathinfo(strtolower($_FILES["file"]["name"])); if(in_array($_FILES["file"]["type"],$allowed_types) && in_array($path_parts["extension"],$allowed_extensions)){ $filename = $timestamp."-".$_FILES["file"]["name"]; echo "Name: " . $filename . "<br />"; echo "Type: " . $_FILES["file"]["type"] . "<br />"; $path_parts = pathinfo($_FILES["file"]["name"]); echo "Extension: " . $path_parts["extension"] . "<br />"; echo "Size: " . round($_FILES["file"]["size"] / 1024) . " Kb<br />"; //echo "Stored in: " . $_FILES["file"]["tmp_name"]. " <br />"; } else { echo "Type " . $_FILES["file"]["type"] . " with extension " . $path_parts["extension"] . " not allowed <br />"; $ok=0; } } if($ok == 1){ @move_uploaded_file($_FILES["file"]["tmp_name"], $target . $filename); $file_location = $target . $filename; if(file_exists($file_location)){ echo "Uploaded to <a href='$file_location'>$filename</a> <br />"; } else { echo "There was a problem saving the file. <br />"; } } } else { echo "Select your file to upload."; } ?> Thanks! hello again need some advice cant get it working Code: [Select] SELECT * FROM `tsue_members` WHERE memberid=0 if ($row['memberid'] == '0') { $img = "1.gif"; } echo $img; The situation is that I have a large string with some identifiers to say "replace me" with something else. My goal is to replace the values, but if one replacement includes one of the other keys, I don't want to replace it.
For example:
<?php $str = 'some blob ~abc~ followed by ~def~'; $arr_orig = array( '~abc~', '~def~' ); $arr_new = array( 'value~def~', 'blah' ); echo str_replace( $arr_orig, $arr_new, $str ); ?>This will echo: some blob valueblah followed by blah But that's not what I'm trying to accomplish. Basically, I want ~abc~ to be replaced with the literal: value~def~ and for the ~def~ that happens to be part of that string to NOT be replaced. I hope what I'm asking is clear. Basically, preg_replace/str_replace with arrays seems no different than just doing a FOR loop and replacing ~abc~ and then ~def~. But that's not what I need. I'm hoping that if ~abc~ is replaced with text that happens to be another identifier -- ~def~, ~xyz~, whatever -- that this already replaced text is not again replaced. Is there a built-in function to do something like this? If not, should I just parse the whole string and count characters or something? Seems like a pain (and slow!) Hi i wrote a find and replace code but my code replace last value of array and skip the first, second.... values in the array. Please give me an idea because i stack with this code. Regards $KeyWord = explode("\n", $RowGetWords['KEYWORDS']); $Replace = explode("\n", $RowGetWords['ReplaceTo']); for($i=0; $i<count($KeyWord); $i++){ $pattern = $KeyWord[$i]; $replace = "<a href=\"" .$URL. "\" target=\"_blank\" >" .$Replace[$i]. "</a>"; $html = str_replace($pattern, $replace, $Row['MessageBody']); } How does wordpress and other similar CMS/applications replace their div elements? For example, if you view the source code of a wordpress site, you will only see: Quote <div id="header"></div> Where, the above code is clearing being switched out for "header.php". How is this done? I believe it's php and jquery, but I would be wrong. Thanks! alright, is this the correct format for a REPLACE INTO? if not what do i need to change.......it isn't working...... Code: [Select] $sql = "REPLACE INTO Events (name, event, eventid, userid, title1, title2, title3, title4, title5, title6, title7, title8, email) VALUES('$name','$event','$eventid','$userid','$title1','$title2','$title3','$title4','$title5','$title6','$title7','$title8', '$email')"; $rs = mysql_query($sql) or die ("Problem with the query: $sql<br>" . mysql_error()); ok so I have an string with data that I need to be replaced with contents from an array. I need the occurance position replace with the index of the array. example Code: [Select] //here is the setup $string = "testing %s one %d %s"; array('this',1,'three'); //here is the result testing this one 2 three the problem I am having is because the %s can occur more than once I cant use str_replace. I am working on a solution with substr_replace but was wondering if anyone had any suggestions on how to do this. When I replace it I also need to run the value through a function so keep that in mind. Also the replace's are stored in an array so they need to be looped through as well. Code: [Select] $replaces = array('%s'=>'func_one','%d'=>'func_two'); Any help is appreciated. User can edit a post. I need to replace the html '<br/>' element to newline character ('\n') .

I am currently using the following code to replace an apostrophe and quote marks when inserting and updating a database record: Code: [Select] $myPageContent = mysql_real_escape_string(str_replace("'", "'", $_POST['myPageContent'])); $myPageContent = mysql_real_escape_string(str_replace("", """, $_POST['myPageContent'])); My question is - how can I modify it so I only need to use one line. Like (but this does not work): Code: [Select] $myPageContent = mysql_real_escape_string(str_replace("'", "'", "", """, $_POST['myPageContent'])); It seems to me that the way I am currently doing it might be POSTing the data twice?

Hello everyone, I'm attempting to find only a specific username in this field "username" located in the database. The code below works when with the rest of the I left out since its not important for this problem. What I would like to do is have it so if I type in the name "john, emily, or chris", and if the name is in the field, then it works. Code: [Select] session_register("username"); // Working code, username is the field name. Ex: Code: [Select] session_register("john | emily | chris"); // Example code, populated with values. I would like to work the same, except with values instead of using the field name. Let me know if you need any further clarification, thank you. hi, im trying to replace an arrays key with its value. this is so i can display the html on the pages. eg: index.html <title>{BOARD_TITLE}</title> index.php $template->replace(array( '{BOARD_TITLE}' => $settings['board_name'] )); template.php(template class) function replace($array) { foreach ($array as $key => $val) { echo $key = $val; } return; } however {BOARD_TITLE} does not get replaced with the value. where am i going wrong?
