PHP MySQL not inserting into database - php

Question

I have heard of this issue but can't seem to figure it out. I have the database and table names correct. I am not finding any errors and i even inserted a table myself on phpmyadmin that worked but when I tried to do it on my site it doesnt work. I even tested the connection..Not sure what to do now
Maybe someone can take a look at my code and see if they notice anything
<?php
if(mysql_connect('<db>', '<un>', '<pw>') && mysql_select_db('smiles'))
{
$time = time();
$errors = array();
if(isset($_POST['guestbook_name'], $_POST['guestbook_message'])){
$guestbook_name = mysql_real_escape_string(htmlentities($_POST['guestbook_name']));
$guestbook_message = mysql_real_escape_string(htmlentities($_POST['guestbook_message']));
if (empty($guestbook_name) || empty($guestbook_message)) {
$errors[] = 'All Fields are required.';
}
if (strlen($guestbook_name)>25 || strlen($guestbook_message)>255) {
$errors[] = 'One or more fields exceed the character limit.';
}
if (empty($errors)) {
$insert = "INSERT INTO 'guestbook'VALUES('','$time','$guestbook_name','$guestbook_message')";
if($insert = mysql_query($insert)){
header('Location: '.$_SERVER['PHP_SELF']);
} else{
$errors[] = 'Something went wrong . Please try again.';
}
} else {
foreach($errors as $error) {
echo '<p>'.$error.'</p>';
}
}
}
//display entries
}
else {
'Fixing idiot';
}
?>
<hr />
<form action="<?php echo htmlentities($_SERVER['PHP_SELF']);?>" method="POST">
<p>Post Somethign</p>
<br />
Name:<br /><input type="text" name="guestbook_name" maxlength="25" />
<br />
Message:
<br />
<textarea name="guestbook_message" rows="6" coles="30"maxlength="255"></textarea>
<input type="submit" value="Post" />
</form>

Answer 1

Remove quotes from table name 'guestbook' and leave a space between it and values

Answer 2

Table name doesn't need quotes and supossing you're using id autoincrement, don't insert an empty string. So it should be:
$insert = "INSERT INTO guestbook VALUES('$time','$guestbook_name','$guestbook_message')";
Also, take a look at your $time value. What MySQL data type is?
After the insert, try to display the mysql error:
$conn = mysql_connect('<db>', '<un>', '<pw>');
mysql_query($insert)
if (mysql_errno($conn)){
$errors[] = mysql_error($conn);
}else{
header('Location: '.$_SERVER['PHP_SELF']);
}
EDIT: The hole snippet should be similar to:
<?php
$conn = mysql_connect('<db>', '<un>', '<pw>')
if( $conn && mysql_select_db('smiles')) //Note $conn
{
$time = time();
$errors = array();
if(isset($_POST['guestbook_name'], $_POST['guestbook_message'])){
$guestbook_name = mysql_real_escape_string(htmlentities($_POST['guestbook_name']));
$guestbook_message = mysql_real_escape_string(htmlentities($_POST['guestbook_message']));
if (empty($guestbook_name) || empty($guestbook_message)) {
$errors[] = 'All Fields are required.';
}
if (strlen($guestbook_name)>25 || strlen($guestbook_message)>255) {
$errors[] = 'One or more fields exceed the character limit.';
}
if (empty($errors)) {
mysql_query($insert)
$insert = "INSERT INTO guestbook VALUES('$time','$guestbook_name','$guestbook_message')";
if (mysql_errno($conn)){
$errors[] = mysql_error($conn);
}else{
header('Location: '.$_SERVER['PHP_SELF']);
}
} else {
foreach($errors as $error) {
echo '<p>'.$error.'</p>';
}
}
}
//display entries
}

Answer 3

you can try below query for insertion:
$insert = "INSERT INTO guestbook VALUES('','{$time}','{$guestbook_name}','{$guestbook_message}')";
