PHP - Double Echo?
This is strange.. I have the following code that checks if there is currently a cap set on requests.
Code: [Select] $result = mysql_query("SELECT cap FROM requests"); while($data = mysql_fetch_array($result)) { if ($data['cap'] == '1') { echo"<h1>Requests are currently disabled at this time.</h1>"; }else{ echo'<h1><a href="requestlivery.php">Request Livery</a> | <a href="requestlogo.php">Request Logo</a></h1>'; } } For some reason, this: <h1><a href="requestlivery.php">Request Livery</a> | <a href="requestlogo.php">Request Logo</a></h1> is printed out twice on the webpage. Like: Request Livery | Request LogoRequest Livery | Request Logo I even put that code on a brand new blank page, and it does the same thing. Any ideas as to why would it do that? Unk Similar TutorialsI have a navigation list displaying which is a mix of html and php, everything is working fine however now I want to convert this block of code into a function but am having major problems with quotes. The line of code I currently have is
$data = $db->query("SELECT * FROM menu")->fetchAll(PDO::FETCH_ASSOC);
foreach ($data as $row) { ?>
<li><a href="<?php echo $row['url']; ?>" title="<?php echo $row['title']; ?>"><?php echo $row['icon'] . ' ' . $row['header']; ?></a></li>
<?php
}
?>
As I say everything works using the above but now I am trying to echo the full li out and am having major issues with single and double quotes. I currently have echo "<li><a href='#' title='the title'><i class='fas fa-user site-nav--icon'></i> Help</a></li>"; Now I am trying to use the $row['url'], $row['title'], $row['icon'] & $row['header'] as per the top example but I cannot get the combination of quote marks correct, whether to use double, single or a combination. I would be grateful if someone could suggest the correct syntax for the a tag then I can work through the rest. Thanks OK, have no idea what's going on... I've done this a million times... why wont this output!?? I must have a major brain meltdown and dont know it yet!!! Code: [Select] <?php // this echoes just fine: echo $_POST['testfield']; // but this wont echo: echo if (isset($_POST['testfield'])) { $_POST['testfield'] = $test; } echo $test; /// or even this DOESNT echo either!: $_POST['testfield'] = $test; echo $test; ?> Hi All, I'm trying to echo the response from an SLA query, the query works and returns the data when I test it on an SQL application.. but when I run it on my webpage it won't echo the result. Please help? <?php $mysqli = mysqli_connect("removed", "removed", "removed", "removed"); $sql = "SELECT posts.message FROM posts INNER JOIN threads ON posts.pid=threads.firstpost WHERE threads.firstpost='1'"; $result = mysqli_query($mysqli, $sql); echo {$result['message']}; ?> I have a log system that allows 10 logs on each side(Left and right). I am trying to make it so that the left side has the 10 most recent logs, then the right as the next 10. Any ideas? So I need to echo a row from my database with php, but where i need to echo is already inside an echo. This is my part of my code: $con = mysql_connect("$host","$username","$password"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("main", $con); $result = mysql_query("SELECT * FROM Vendor"); while($row = mysql_fetch_array($result)) { //I need to echo right here .................. but I get a blank page when I try this. Please Help. echo '<option value=$row['vendor_id']>'; echo $row['vendor_id']; echo '</option>'; } mysql_close($con); Result: A Blank page. Thanks in advance! Hi
I try to echo out random lines of a html file and want after submit password to whole content of the same html file. I have two Problems.
1st Problem When I echo out the random lines of the html file I don't get just the text but the code of the html file as well. I don't want that. I just want the text. How to do that?
for($x = 1;$x<=40;$x++) {
$lines = file("$filename.html");
echo $lines[rand(0, count($lines)-1)]."<br>";
}
I tried instead of "file("$filename.html");" "readfile("$filename.html");" But then I get the random lines plus the whole content. Is there anything else I can use instead of file so that I get the random lines of text without the html code?P.S file_get_contents doesn't work either have tried that one.
2nd Problem:
As you could see in my first problem I have a file called $filename.html. After I submit the value of a password I want the whole content. But it is like the program did forget what $filename.html is. How can I make the program remember what $filename.html is? Or with other words how to get the whole content of the html file?
My code:
if($_POST['submitPasswordIT']){
if ($_POST['passIT']== $password ){
$my_file = file_get_contents("$filename.html");
echo $my_file;
}
else{
echo "You entered wrong password";
}
}
If the password isn't correct I get: You entered wrong password. If the password is correct I get nothing. I probably need to create a path to the file "$filename.html", but I don't know exactly how to do that.
Hey guys i need to generate a table for a multilevel marketing simulation of 10.000 members. It's a bi-level. All i need is a table with id, parrent I am lost with the double loop ... if u use this for one condition if ($nr > 5) how would u check if the nr is between 5 and 50 thanks ! Can someone please tell me what i have got wrong here? I am trying to return value C if conditions a AND B are met or return value D. Not sure if its parenthesis or something else? <?php if (($row_Recordset4['multidirection']=="yes") && ($_POST["widthcheck"] < $row_Recordset4['drop'])) echo $row_Recordset4['width'];else echo $row_Recordset4['drop'] ?> Thanks sorry, I posted twice. Why is double spacing the results I know it's stupid simple but I can't see it. I removed $host ip so if you test put one in there.

please help me with this.since i started posting this form to its self it has been inserting values twice into the database when the user clicks submit button and i also noticed that i have to refresh the page before inserted comments can be showed.this is my code: Code: [Select] <?php include"header.php"; $sql="SELECT post_content,post_by FROM post WHERE topicsID='$tpid'"; $result=mysql_query($sql)or die(mysql_error()); while($row=mysql_fetch_array($result)) { echo"<strong>{$row['post_by']}</strong>: {$row['post_content']}"."</br>"; } ?></td> </tr> </table> <?php include"header.php"; if(isset($_POST['submit'])) { $comment=mysql_real_escape_string(trim($_POST['comment'])); $name=mysql_real_escape_string(trim($_POST['name'])); $hidden=$_POST['id']; if($comment!=='' && $name!=='') { $topicid=$_GET['id']; $ins="INSERT INTO post(post_content,post_by,post_id)VALUES('$comment','$name','$topicid')"; mysql_query($ins) or die(mysql_error()); } else { echo"you cannot post an empty field"; } } ?> <h3>Post your comments here</h3> <form action=''method='post'> <textarea name="comment" id="content" style="width:400px;height:50px;background-color:#D0F18F;color:#000000;font:15px/20px cursive;scrollbar-base-color:#638E0D;"></textarea> <br /> Name:<input type="text"name="name"/> <input class="button" type="submit"name="submit"value="submit" /> </p> </form> I am wondering since in php when you write string in " " quotes php will look if there is any variable and if it is it will read that variable and replace variable name with that value inside the string. However when i use ' ' quotes php will not look for any variables inside that string. So my question is when you write a really big application is it good to always use ' ' quotes when you can instead of " " ones. Does that have an impact on performance. Thanks How do I apply double delete verification? Right now I have... Code: [Select] if (isset($_POST['delete'])) { if(is_array($_POST['delete'])) { $keys = array_keys($_POST['delete']); $id = $keys[0]; $sql = "DELETE FROM `blog_posts` WHERE `post_id` = '$id'"; header("Location: " . $_SERVER['php_self'] . "?" . $_SERVER['query_string'] ); } } if(isset($sql) && !empty($sql)) { mysql_query($sql) or die(mysql_error()); } which deletes the query great, but I want some box to pop up saying, are you sure you want to delete this post? I'm not sure how to create this verification. Hi All, I was wondering if someone maybe knows a nice way to prevent double posting or posting within a certain time without using javascript. Or maybe even echoing an error if someone posts the exact same ase the previous post. I found this little snippet: Code: [Select] onClick="disabled=true;this.form.submit();return true;" Which prevents double clicking. But its javascript and I rather have something besides that to cover all situations. Would love to hear what you guys use or reccomend. Thanks! I'm designing a website that takes user input from in a <textarea></textarea> and enters the input into a database. Everything works besides if the user has double quotes (") in his/her message. (the name of the table that I want to add to is alluserposts) What i have so far is the following: from index.php: <form action="insert2.php" method="post"><textarea name="user_post" rows="6" cols="35"></textarea></form> from insert2.php: mysql_query("INSERT INTO alluserposts (post_value) VALUES(" . "\"" . $_POST['user_post'] . "\")" ,$db) or die(mysql_error($db)); I want the user to be able to input any character. How can i do that? hi, i have a script that inserts a csv into mysql. i run into errors when there is an empty field example: Code: [Select] filed1,field2,field3,,field5,,field7 here is my code that processes it. Code: [Select] $handle = fopen("uploads/$filename", "r"); while(($data = fgetcsv($handle, 1000, ",")) !== FALSE) { $import .= "INSERT into goaliestats(id,name,gp,w,so,gaa,date) values(NULL,'$data[0]','$data[2]','$data[8]','$data[26]','$data[18]','$data[28]')" . "\n"; mysql_query($import) or die(mysql_error()); } fclose($handle); is there a way i can make a ,, into ,0, ? thanks! I was looking over some php code, and came across this: $c=($c*$j)<<2; I have never see << before, what does it mean/do? Hello, its a bit difficult to explain the issue that I have but I will try my best. I have this small code $message = $_POST['message1']; in my php code and message1 is the name of a textarea in my page. i also have another textarea called message2 in my page. what I need to do is to use the message1 and message2 in the $message = $_POST function. For example: $message = $_POST['message1'] + $_POST['message2'] or anything that is acceptable in PHP coding and works in PHP. I hope I havent confused you guys and you undersstood what I mean... Thanks |
