PHP - Is This A Common Thing? Issue With "<?php Echo $php_self;?>"

Hi guys

I am a newbie with PHP and I have been trying to solve this problem for 3 days..

Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button..
The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears
"Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27"

When I check online I have this message "500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed."

Are my codes wrong???

My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland

Thanks for your help!

Hi guys

I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words.


$find = "left";
$replace = array("up","down","forward","backwards");
$text = "left left left left";

echo str_replace($find,$replace,$text);


The Output is: array array array array

Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? 

Thanks

Hi all - I am a novice when it comes to PHP, but I have managed to use it successfully many times. I have an issue where I can not get a variable to echo when I am calling it from within a file that is using SSI. Here is a basic example that should explain it better.

In the /index.php file:
Code: [Select]
<?php 
 $photo1="photo1.jpg";
 $photo2="photo2.jpg";
 ?>

<?php include('http://www.DOMAIN.com/includes/header.php'); ?>

In the /header.php file:

<img src="http://www.DOMAIN.com/photos/<?php echo $photo1; ?>">




When I try to echo $photo1 from within the /header.php file it simply does nothing, even though the variable is declared before the call for the include file.

If I try to do the echo with the IMG tag from within the /index.php file, it works no problem -but that wont work without a MAJOR site redesign with how things are configured.

Question is, why does this not work, and how can I fix it?

Huge thanks from this Newb!

Good evening --

My script takes a while to execute as it processes records from the db.  I'd like to have it print out to the screen the record id # as it processess each record, just to let me know where it is.  Currently, the program waits till the end and then prints out the record numbers, which is no help.  How can I enable PHP to print out each record number as it goes along?

Thanks!

Hello, all...

I seem to remember, like if I have a problem with a mysql_query() statement, and want find out why it keeps giving me an error, I'm often told to echo out the statement for debugging purposes. Can somebody remind me again how that's done...

thanks!

cant work out this mysql syntax error
"operation":"medupdate","medid":"","name":"ibo","medyear":"5","medmonth":"21","medday":"1","recuser":1,"SuccFail":"fail","SuccFailMessage":"error occured You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '''WHERE med_id=' at line 2","ResultData":""}

Code: [Select]
$sql="update metodology set med_description='".$req['name']."',
  med_year='".$req['medyear']."', med_month='".$req['medmonth']."', med_day='".$req['medday']."', med_recorddate= now(), med_recorduserid= 1'";
  $sql.= " WHERE med_id=".$req['medid'];

I have written code so that when something from a MySQL field equals 0, then PHP will take no action, and if the field equals anything else, then 'echo "foo"'.
The problem I am having is that when PHP echo's nothing (echo ""), its still creating the effect of a HTML <BR>.

Screen shots:

1. When the MySQL table contains something else than 0 (echo "foo").

2. When the table contains 0 (echo "").
http://i53.tinypic.com/2h5jg4k.png

3. What it should look like if the table were to contain 0 (echo ""). Note that their is no <BR> effect.

Code:
$query = "select sizes from products where id='$id'"; $result = mysql_query($query); $data = mysql_fetch_array($result); if ($data['sizes'] == 0) {echo "";} else {echo "Small - ".$data['sizes'];}

Is it possible to make it so if a MySQL field result equals 0, then PHP will not produce the HTML <BR> effect when it echo's nothing (echo "")?

I am running through a tutorial and I am getting an error based on a the concatication operator on my output. Below is my code.

As you can see I am echoing $display_block .= "<p>$title<br>$rec_label<br>....

If I send this as-is I get this error: Notice: Undefined variable: display_block in C:\wamp\www\php\php_mysql\sel_byid.php on line 36

I can resolve the error by placing this before the while loop: $display_block = "";

Is there a better way to output the concatenation.= so I don't need to do this weird fix?



while ($row = mysql_fetch_array($result))
{
$id = $row['id'];
$format = $row['format'];
$title = stripslashes($row['title']);
$artist_fn = stripslashes($row['artist_fn']);
$artist_ln = stripslashes($row['artist_ln']);
$rec_label = stripslashes($row['rec_label']);
$my_notes = stripslashes($row['my_notes']);
$date_acq = $row['date_acq'];

if ($artist_fn != "")
{
$artist_fullname = trim("$artist_fn $artist_ln");
}
else
{
$artist_fullname = trim("$artist_ln");
}

if ($date_acq == "0000-00-00")
{
$date_acq = "[unknown]";
}

$display_block .= "<p>$title<br>$rec_label<br>$artist_fullname<br>$my_notes<br>$date_acq<br>$format</p>";

I am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?

Just started.  I am pretty sure composer.json wasn't changed.  journalctl doesn't show anything.  Maybe Doctrine related, however, nothing seems to help.

Any ideas?

I know this is stupid newbie stuff, but I can't think about this the right way.  And this question might very well make NO sense. If so, I apologize in advance.  I'm trying to consolidate code.  I basically have lots of quizzes, all with their own answers, which I compare using AJAX.  I had individual pages for each quizzes answers to do that comparison and everything was working fine.  It would do the following...
Code: [Select]
<?php
$userinput = strval($_GET['userinput']);
$userinput= trim($userinput);
$userinput = strtolower($userinput);

switch ($userinput) {
     case 'heat':
 case 'miami heat':
          echo 'Miami Heat';
          exit;
     case 'magic':
 case 'orlando magic':
          echo 'Orlando Magic';
          exit;
     case 'jazz':
 case 'utah jazz':
          echo 'Utah Jazz';
          exit;

        
     default:
          echo 'incorrectguess';
}
?>
But now I am storing the answers in a MySQL database (for example, one answer set is in the database as "Miami Heat/heat/miami"...each allowed answer is separated by a "/", with the first answer being the "main" correct answer).  So now, I want to just have ONE "comparison" page and populate the "cases" into that page dynamically, from the database.  This is what I came up with so far, but it's not working...

Code: [Select]
<?php

$userinput = strval($_GET['userinput']);
$userinput= trim($userinput);
$userinput = strtolower($userinput);


if ($_GET['quizid'] == "") {
redirect_to('index.php');
} else {
$quizid=$_GET['quizid'];
}

$sql = "SELECT * FROM answers
WHERE quizid = $quizid";
$result = mysql_query($sql, $connection);
if (!$result) { 
die("Database query failed: " . mysql_error());
} else {

switch ($userinput) {

while ($results = mysql_fetch_array($result)) {
$answers = explode("/", $results['answer']);
$n = count($answers);
for ($i=1; $i < $n; $i++) {
case '$answers[$i]':
}
echo '$answers[0]';
exit;

 
 default:
echo 'incorrectguess';
  
}

}
?>

What I'm having trouble grasping is where I need to use "echo" or NOT use "echo".  For example, where I have "switch ($userinput) {" in the NEW code, does that need to actually be "echo 'switch ($userinput) {';"?

I'm trying different combos and failing, so just curious if someone can help me understand what, if anything, needs to be echoed when doing it the 2nd way (dynamic info) rather than the 1st way (static info)

How do i get the page to echo a message after my user's have registered?

i was thinking it goes under the query like this, am i correct?:

Code: [Select]
$query ="INSERT INTO `companies` (company_name, what_services, website, contact_name, location, postcode, street1, street2, city, phone, email, premiumuser_description, username, password, salt, approved, upload) VALUES ('$company_name', '$what_services', '$website', '$contact_name', '$location', '$postcode', '$street1', '$street2', '$city', '$phone', '$email', '$premiumuser_description', '$username', '$password', '$salt', '$approved', '$upload')";
$result = mysql_query($query) or die(mysql_error());
if ($result) {

  echo('Thanks, your now registered');

using the if statement?

any help would be appreciated, many thanks. 

Hello,

I am guessing that this is a totally noob question and I am sorry about it. I am not someone who is familiar with php. I just can see what code says sometimes. I have a wordpress file which I wanted to edit. I was successful until I hit this line of code.

<?php echo "\n" . installedtheme::frontSections( ); ?>

This code is responsible for entire front page structure. When I delete this line my front page gets empty. In html side I can see </section> parts which I want to exclude but select what to exclude from code. I am guessing this echo calling a file that is told as front sections. I am lost. Is there any way to find and edit this file?

 

Thanks for help.

I have a field in my database called `intro` In this field the user has entered spaces, different paragraphs and ""

When it was entered into the field it was run through trim and mysql_real_escape_string. when its echoed I am just using

echo "member['intro'];

How do I make it display like it was entered?  Is there a function for this?

Code: [Select]
if (empty($_POST['selected_messages']))
message($lang_pms['Must select']);

$idlist = array_values($_POST['selected_messages']);
$idlist = array_map('intval', $idlist);
$idlist = implode(',', array_values($idlist));

// If you're not the owner of the message, you can't delete it.
$result = $db->query('SELECT DISTINCT sender_id FROM '.$db->prefix.'messages WHERE id IN ('.$idlist.') AND folder="sent" ') or error('Unable to delete the message', __FILE__, __LINE__, $db->error());
Okay, as you can see it makes intval for all the $_POST['selected_messages'] , but the problem is, when I use tamper data and just add a form field "selected_messages" it brings up a mysql error and the $idlist is blank..


so is there a way to make sure that the $_POST['selected_messages'] has to equal 'selected_messages[]' OR show error?

people can just tamper data and use selected_messages without the [] and it brings up a mysql error, that's not good, I don't want users seeing my code



edit:

WOW

Code: [Select]
if (empty($idlist)){
message("No Permission");
}
fixed it

sorry
