PHP - Oop & Variable Passing & Function Calls
http://pastebin.com/DbHQSYd7
Been stumbling my way through OOP and seem to be understanding it for the most part (I think..) But I've got a couple questions / kinks that I can't seem to work out. a) How do I return a variable from a class so that a different class has access to it (meta_data) b) I'm getting a "$this" cannot be redefined error (which I know why, but I don't know how to fix)) c) How do I call a function from within one class, where the function resides in another class, AND pass it variables? Any help would be greatly appreciated I've tried to Google warrior A and I think I can figure that one out, but B and C are proving to be the real stumbling blocks. Similar TutorialsHelp I am trying to pass a php variable into a javasript function. Here is my code.
<a href="<?php echo $row['track']; ?>" download="<?php echo $row['track']; ?>" onclick="myhit(<?php echo $row['track']; ?>)">Download</a>
<script>
function myhit(top){
alert(top);
}
</script>
the javascript function is never called
I everyone, I'm developing a small MVC framework for my personal work, now, in order to have access from all the classes to certain variables I've created a registry class, for this to work I have 2 options: 1.- passing every time the registry object to the constructor class(controllers, models, etc) or 2.- create in the registry static set and get so I can reach the variables by Registry::set(name, value) and Registry::get(name) My question is, which one of this two options takes less resources(is faster)? I hope anyone can help me with this, thanks in advance I have this code that has Code: [Select] $this->BeginTransaction();all over it. These are in classes where no such function is defined, and they don't have parents either. It's driving my crazy trying to figure out why they are there, why there's not so much as a warning being given and what, if anything, is being called. Now I do have a Code: [Select] set_error_handler("amfErrorHandler");and in amfErrorHandler I have Code: [Select] if( error_reporting() != 0 && ($amfphpErrorLevel | $level) == $amfphpErrorLevel ) { throw new VerboseException($string, $level, $file, $line); } I don't remember what $amfphpErrorLevel is, except that it should only be ignoring things like E_STRICT. Also, no exception is being thrown. So what do I do w/this code? but never on the first call. Okay, I posted this on StackOverflow but no one there seems to have an answer either. I have this simple function: Code: [Select] public function delete($messageID) { $type = $this->findType($messageID); if ($type == 'in') { foreach ($this->inArr as $key => $value) { if ($this->inArr[$key]->messageID != $messageID) $implodeData[$key] = $this->inArr[$key]->messageID; } if (!isset($implodeData)) $imploded = '0'; else $imploded = implode(',', $implodeData); $result = $this->_database->updatePMUser('inArr', $imploded, 'UID', $this->UID); $result2 = $this->_database->deletePM('messageID', $messageID); return; } else { foreach ($this->sentArr as $key => $value) { if ($this->sentArr[$key]->messageID != $messageID) $implodeData[$key] = $this->sentArr[$key]->messageID; } if (!isset($implodeData)) $imploded = '0'; else $imploded = implode(',', $implodeData); $result = $this->_database->updatePMUser('sentArr', $imploded, 'UID', $this->UID); $result2 = $this->_database->deletePM('messageID', $messageID); return; } } It is a delete function for a private messaging program for a forum script I'm writing. Anyway, here's the issue - it works! But only sometimes. It is called in 3 different places, always from a form processing class I have, once in the view message section to delete a message you're viewing, in a foreach from the sentbox options section and then a foreach in the inbox options section. The inbox and sentbox option sections do that whole "delete the checked messages" for the mass removal functionality. The delete function above works in all ways shapes and forms when I use it in single calls - like when I'm deleting a message while viewing it or when I only check one message from the inbox, etc - but when I call it multiple times (as in I have checked multiple messages) - it fully deletes one (both the message and the reference to the message in the user's db row) and then only deletes the actual message on the others (deleting the message is the call to deletePM - deleting the reference is the call to updatePMUser). Okay, if you need further information - the function above checks the type the message is (in the inbox or in the sentbox) and then uses that to foreach through that array (inArr or sentArr) of the user. It logs in all the messageIDs of the those that DON'T match the one we're deleting and then at the end it implodes those caught IDs into a string that is then updated in the user's row as a comma separated string of values each representing a message in the DB - you get the picture. I realize I have some trimming to do (for one I can cut the above function down by about half by using variable variables) but I'll get to that after I get the thing working. I can't figure out why it's doing what it's doing. If you need the function that calls this in the foreach, I have it below. Oh, and the thing that really boggles me is that this function is called fully for each checked message in the foreach - it fully returns and then loops - if it works once, I don't see how it wouldn't work on a second call from a loop - the variables it uses should be trashed when it leaves the function, they aren't global or object properties or anything. Color me confused. Thanks for any help, oh, here's one of the functions that calls it to delete checked messages (this one is for the sentbox, there is another for the inbox): Code: [Select] private function _processSelectedSent() { $pmObj = unserialize(base64_decode($_POST['pmObj'])); $i=1; foreach ($_POST as $key => $value) { if ($value == 'marked') { $checkedArray[$i] = $key; $i++; } } if ($_POST['submitter'] == 'Delete Selected') { if (is_array($checkedArray)) { foreach ($checkedArray as $key => $value) $pmObj->delete($value); } else $pmObj->delete($checkedArray[1]); header("Location: ".HOME_PAGE.PM_PAGE."?view=sentbox&nocache=".time()); } } Trying to set up an error message when someone tries to upload a file without the approved .ext. I have it working so it won't up load but I am trying to get an error to print out. I was thinking that I could do something like this if the ext are wrong set $errorMsg1 == 1; and then the page will refresh and I would pass that variable to echo out if ($errorMsg1 == 1){ echo "Invalid"; } else { but it isn't passing can anyone help me with this? Tyring to keep it simple this is the code to select an image else{ $result = mysql_query("SELECT * FROM photos WHERE userID LIKE '$clientID'"); while ($r=mysql_fetch_array($result)) { $photo_1=$r['photo_1']; $photo_2=$r['photo_2']; $photo_3=$r['photo_3']; $photo_4=$r['photo_4']; $photo_5=$r['photo_5']; echo " <form enctype='multipart/form-data' action='' method='POST'> <input type='hidden' name='MAX_FILE_SIZE' value='500000' /> <div id='imageTop'>Image &#35;1</div> "; if ($errorMsg1 == 1){ echo "Invalid"; } echo " <div id='imageBottom'> <span class='image'>"; if (empty($photo_1)) { echo " <img src='uploads/noPhoto.gif' width='75' height='75' class='zip'> "; } else { echo "<a href='uploads/$photo_1' ><img src='uploads/$photo_1' width='75' height='75' class='zip'></a> "; } echo " </span> <span class='action'> <input type='file' name='photo_1' class='zip'><br><br> <input type='checkbox' name='delete_1'>Select to Delete image </span> </div> } this is the code of what to do with that image if (isset($_POST['delete_1'])) { $query = "UPDATE photos SET photo_1='' WHERE userID='$clientID'"; $result = mysql_query($query) or die(mysql_error()); echo " <div id='aboutUpdate'><img src='img/loader.gif'> Information is updating</div> "; echo "<meta http-equiv=refresh content=\"0; URL=photos.php\">"; } else if ($one != NULL) { $extension = strrchr($_FILES['photo_1']['name'],'.'); $extension = strtolower($extension); if($extension != '.jpg' && $extension != '.gif' && $extension != '.png' && $extension != '.bmp' ){ $errorMsg1 == 1; echo "<meta http-equiv=refresh content=\"0; URL=photos.php\">"; } else { $photoNumber="_1"; $finalName="$clientID$photoNumber"; $save_path = "uploads/"; $target_path = $save_path . basename( $_FILES['photo_1']['name']); $NewPhotoName = $finalName; $withExt = $NewPhotoName . $extension; $filename = $save_path . $NewPhotoName . $extension; if(move_uploaded_file($_FILES['photo_1']['tmp_name'], $filename)) { $query = "UPDATE photos SET photo_1='$withExt' WHERE userID='$clientID'"; $result = mysql_query($query) or die(mysql_error()); echo " <div id='aboutUpdate'><img src='img/loader.gif'> Information is updating</div> "; echo "<meta http-equiv=refresh content=\"0; URL=photos.php\">"; } } else { Hi, can anybody please tell me how i can make "Arson" into a php variable Code: [Select] <script type="text/javascript" src="js/swfobject.js"></script> <script type="text/javascript"> swfobject.embedSWF( "open-flash-chart.swf", "my_chart", "550", "400", "9.0.0", "expressInstall.swf", {"data-file":"ofc-chart.php?crime=Arson"} ); </script> Hi, I am trying to pass a variable when posting a form. This is my form with the select: Code: [Select] <form id="form1" name="form1" method="post" action="products_2.php?id_subcategoria= WHAT SOULD I PUT HERE?"> <select name="subcats" class="subcatsSelectMenu" id="subcats" onchange="this.form.submit()"> <option value="">Ver placas por tipos</option> <?php do { ?> <option value="<?php echo $row_subcats_RS['id_subcategoria']?>"><?php echo $row_subcats_RS['subcategoria_esp']?></option> <?php } while ($row_subcats_RS = mysql_fetch_assoc($subcats_RS));$rows = mysql_num_rows($subcats_RS); if($rows > 0) { mysql_data_seek($subcats_RS, 0); $row_subcats_RS = mysql_fetch_assoc($subcats_RS); } ?> </select> </form>How can I pass the variable in the URL? Thanks This is driving me MAD! The Variable gets passed through the URL but when I try and echo the result I gte NOTHING. First Page. Code: [Select] <?php include'config.php'; $result = mysql_query("SELECT * FROM carbontrust"); while($entry = mysql_fetch_array($result)) Print "$entry[contact] - $entry[company] :: <a href='edit.php?id=$entry[id]'>Edit</a><br>"; exit; ?> Second Page. (Where I want the Variable passed to) Code: [Select] <?php include'config.php'; $id = $_GET['id']; echo "ID: $id"; } ?> Its probably just a stupid error but iv looked through a load of tutorials and this should be correct. :/ How, if possible, can a $var be passed to the forms action php file? I tried everything with no success. Edited December 24, 2019 by cyberRobotRemoved email address hello all, I'm new here and I'm learning mysql/php. Currently I have a dynamic table on one of my webpages, and the loop code looks like this:while ($i < $numRows) { $fname = mysql_result($result, $i, "fname"); $fcode = mysql_result($result, $i, "fcode"); $ftype = mysql_result($result, $i, "ftype"); $fdesc = mysql_result($result, $i, "fdesc"); ?> <tr> <td><a href="showfunction.php?fname=<?php echo "$fname"; ?>" target="_self"> <?php echo "$fname"; ?></a></td> <td> <?php echo "$fdesc"; ?> </td> <td><div align="center"> <?php echo "$ftype"; ?> </div></td> </tr> <?php $i++; } ?> what I would like to do is pass the ''fname'' variable to the "showfunction" page so it can printed from the database. Here is the relevant portion of the page:<body><div class="codeblock"> <div class="title">Code:<br /> </div><code><pre> <?php echo $fcode; ?> </pre></code></div> <br /><pre><hr /> </pre> I know that doesn't work, and I didn't expect it to because there is no way to 'get' the 'fname' variable from the preceeding script. I do not want to use the GET method with this because from what I understand, you can only use it with Forms. I really don't want to put controls in all of my table fields just to be able to pass the function name to the next page. Does that make sense? If I could get a jumpstart on this one last hurdle, I would appreciate it. thank you so much! Cheers. The below script for some reason isn't passing along the product_id variable.

I just want some nice person to give me the answer. I'm trying to pass a variable using href to another page. It works great if the variable is only one word. But it only passes the first word. There are multiple posts on this topic, but I can't seem to get any of those fixes to work for me. Here the code. Code: [Select] <?php $query = "select DISTINCT city from daily where open_bid>0 order by city ASC"; $result = mysql_query($query); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $details=''; $details.='<li class="menu"><span class="name"><a href=list.php?city='.$row['city'].'>'.$row['city'].'</a>'; $details.='</li>'; echo($details); } ?> As you can imagine, some cities names are made up of two words. This is only passing the first word. Thanks for your help. I had an iframe working for the last few months on a site at hostgator. Yesterday, it quit working (403 permissions error). After a long bout of trouble-shooting, I found out that it has something to do with mod_security that they have suddenly enabled (have no idea as I'm not a Linux guy). They told me they fixed the problem on my domain by whitelisting it as an exception, but strangely, even though the permissions error went away, the actual src= box of the iframe, which was the url variable I was passing in the url, no longer loads. So.. I'm trying to break this down into the simplest form to figure it out. I just understand php basics so needing some verification that I'm doing this right/wrong. Here's my code.. page1.php Code: [Select] <? $testurl = "http://google.com"; ?> <a href="http://mysite.blah/page2.php?url=<? echo $testurl; ?>">page2.php</a> page2.php Code: [Select] if (isset($_GET['testurl'])) echo $testurl; else echo "sorry dude"; I am only able to print "sorry dude". Am I doing something wrong or shouldn't this send the url?

<script type="text/javascript" src="jquery-1.11.min.js"></script> Okay, I have been looking into this for the last 3 hours, and cant find shit. I have a page with a javascript game where the player moves around on a map. They have an X and Y coordinate, but I'm having a problem. The problem is I need to store that info in a database, and I'm having trouble learning AJAX. Heres a little list of things: Play loads the game. A php variable is taken from a database. The player goes to those X and Y coordinates. The player may move around. Once they move, the player is sent to a php page that updates the Database information. The page is refreshed to the game again, where they may then move around some more. The problem is, when the page is changed the values are lost. For some reasons cookies aren't working at all (like just not working for anything, even a completely different file.) I heard something about using $_GET or $_POST, but I dont see how... i have this code in a form, i need to pass a variable $time to next page, how can i do that ? if( $sErr ) print "<script language='javascript' type='text/javascript'>location.href='#error';</script>";;; else: print "<script language='javascript' type='text/javascript'>location.href='paypal.php';</script>";;; Hello, I'm trying to build a small project; and as part of it - I want users to search and when presented with relevant enteries in the SQL database - they should be able to click and retrieve a page dedicated to that entity. The problem I am having is in passing the 'id' of the search result onto the next (description) page. Code: [Select] $SQL = "SELECT * FROM loads"; $result = mysql_query($SQL); while ($db_field = mysql_fetch_assoc($result)) { $clickid = $_GET['id']; print $db_field['id'] ."<a href=\"load_info.php?id=$id" . $id . "\" target=\"_self\" title=\"\">More Info</a>;"; print $db_field['depart:'] . "<BR>"; print $db_field['dest'] . "<BR>"; } I thought it was easy enough to pass the variable like above ("load_info.php?id=$id) and then grab it on the next page like so: $val = $_GET['clickid']; Unfortunately, it doesn't retrieve the info from the page before. If I insert a number in there, it does work correctly, but I really need the ID of the database entry to pass on so as to provide the user with further information. If anyone could help it would be appreciated. L. Please forgive my limited knowledge of php. I am trying to pass a variable from 1 page to the next. I have SCRIPT A (I didn't write it) that parses an rss feed and then calls SCRIPT B to insert it into a database. Everything works great.. and all I'm trying to do is add a new piece of information. In my db, I added a column called 'city'. There are currently 25 different SCRIPT A's (25 different city names). I could create 25 SCRIPT Bs and call them individually, but I'm trying to use 1 SCRIPT B and just send the city name. I've read about POST and GET but still not sure on this? Can't I just hard code my city name into each SCRIPT A like this: Code: [Select] $city = "miami"; And then put this at the top of SCRIPT B? Code: [Select] $city = $_GET['city']; Well.. apparently, I can't because that doesn't work. Again.. sorry for the dumb question. It's my first time attempting anything with php. Thanks. |
