Check if file exist before print - php

Can someone help me connect some code??
What I want is a code that does this: If a picture exist then print it, else don't print anything.
(This code is used to find the pichure)
and I need help to conect the if statment to the one in the other code
<?php
$pathToFileOnDisk = 'inventory_images/' . $id . '.jpg';
if(file_exists($pathToFileOnDisk) && is_readable($pathToFileOnDisk)) {
<img src="inventory_images/' . $id . '.jpg" alt="' . $name . '" width="100%" height="260" border="1" />
}
else {
// NO IMG
}
?>
AND
<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors', '1');
?>
<?php
// Run a select query to get my letest 6 items
// Connect to the MySQL database
include "storescripts/connect_to_mysql.php";
$dynamicList = "";
$sql = mysql_query("SELECT * FROM content ORDER BY id DESC LIMIT 6");
$productCount = mysql_num_rows($sql); // count the output amount
if ($productCount > 0) {
while($row = mysql_fetch_array($sql)){
$id = $row["id"];
$name = $row["name"];
$content = $row["content"];
$date_added = strftime("%d %b, %Y", strtotime($row["date_added"]));
$dynamicList .= '<table width="100%" border="0" cellspacing="0" cellpadding="0">

Use the file_exists() and is_readable() functions.
The first will tell if the file exists, and the second will tell if you have permissions to read the file, before actually doing it. Similarly, there's also the is_writable() function, which tells you if you have permissions to write to a file.

Simply use this:-
<?php
$filename = 'some_name';
if (file_exists($filename)) {
echo "File exists";
} else {
echo "File does not exist";
}
?>

The file_exists and is_readable functions are perfect for this purpose.
For example:
<?php
$pathToFileOnDisk = '/full/system/path/to/image.jpg';
if(file_exists($pathToFileOnDisk) && is_readable($pathToFileOnDisk)) {
// The file exists and can be read
}
else {
// The file doesn't exist (or does exist, but PHP can't read it).
// Perhaps output a placeholder image here.
}
?>
Incidentally, I'd recommend a quick glance at all of the filesystem functions, as the time spent on this now will pay dividends in the future.

I have problem with my (made with tutorial) PHP comment box.
The problem is this number 1. I think that problem is in last code, but as I am beginner I don't know where is problem.
I'm posting all 3 php files without header and footer file.
PrtSc of problem on page
Source code in chrome of page
This is full code in php....
First php file
<?php

Next file which is connected through "include" is:
<?php include('Header.php'); ?>

And last file for Mysql, same included is:
<?php

$Komentar=$rows['Komentar'];
echo $Ime . ':<br/>' . $Komentar . '<br/>' . '<br/>' . '<hr size="4"/>';}

Thank You in Advance!
As include language construct returns 1 on successful file including - this value is passed to your echo, so line:
echo include('novo_Mockingjay2_komentar.php');
means - include file, execute it and echo the result of inclusion. As result is 1 - it's echo'ed.
Change it to:
include('novo_Mockingjay2_komentar.php'); // without echo

Selecting table and trying to query results with PHP is not working

I have a database which contains 2 tables. In the second table there are numerous records and I'm trying to echo out the latest id (MAX id) to the page using PHP. There is something wrong with my code and I don't know what that is:
$sqlCount = "SELECT MAX(id) FROM records";
$sql = "SELECT id,preview,description FROM records";
$pn = (isset($_GET['pn'])) ? $_GET['pn'] : 1;
$res = upagination($con, $sql, $sqlCount, $pn, 6);
$list .="<table border=0>";
foreach ($res['rows'] as $row) {
$list .="<tr>";
$list .="<td>" . $row['id'] . "</td><td>" . $row['preview'] . "</td><td>" . $row['description'] . "</td>";
$list .="</tr>";
}
$list .="</table>";
$paginationCtrls = "";
if (isset($res['backLink'])) {
$paginationCtrls .= "Previous";
}
if (isset($res['numbers'])) {
foreach ($res['numbers'] as $number) {
if ($number === $res['current']) {
$paginationCtrls .= "$number";
}
(some deleted code to shorten this a little)
}
}

put items into an array based on punctuation

I am working on a way to pull data from my mySQL database and display the text as an array however I have it so that only one string of data is available and each instance is separated by a comma example. 1,2,3,4 is there a way to have it break or start a new line after each comma instead of having a conglomerated mess that looks like this:
1 package KRAFT Deluxe Macaroni & Cheese Dinner Sharp Cheddar Cheese Sauce, 1 lb Ground Beef, 1 Jar Spaghetti Sauce, 1/2 Cup KRAFT Shredded Mozzarella Cheese

If I got it correctly you just need something like this:

display image in my page using echo [duplicate]

This question already has an answer here:
upload image to mysql database php
(1 answer)
Closed 9 years ago.
this is code of the page that I will get the image from(work perfectly)
<?php
ob_start();
session_start();
include('connect.php');
$id = $_GET['id'];
$query = mysql_query("SELECT * FROM news WHERE id=$id");
$row = mysql_fetch_assoc($query);
header("Content-type: image/jpeg");
echo $row['image'];
?>
and this is my page that i get the image to in
<?php
ob_start();
session_start();
include('includes/connect.php');
include('includes/phpCodes.php');
$id = $_GET['id'];
function showNews() {
$data = array( 'id' => $id );

i think my wrong is in , can someone tell me how can I solve it?, sorry for my bad english
Cleared it up for you:
echo '<img src="includes/getImage.php?id=' . $id . '" class="newsImage">';
Should 100% work (if the $id param has a value of course).
Update to fix the missing $id var:
<?php
ob_start();
session_start();
include('includes/connect.php');
include('includes/phpCodes.php');
$id = $_GET['id'];
function showNews(){
$id = $_GET['id'];
$base = "includes/getImage.php";
$url = $base. "?" . "id=36";
echo $url;
echo '<img src="includes/getImage.php?id=' . $id . '" class="newsImage">';
echo '
<h1><p class="subjecTitle">??? ???????</p></h1>
<div class="newsContent"></div>
';
}
?>
why are you using two different pages?
put both code in single page and simply do this
<img src=includes/<?php echo $row['image']; ?> class="newsImage">
Change :
echo ' <img src=includes/getImage.php class="newsImage">';
To :
echo ' <img src="includes/getImage.php?id='.$id.'" class="newsImage">';
Please note src has " and also make sure that includes/getImage.php return a image path

Set Page Title using PHP

I wish to set the title of my webpage to Ultan.me - Whatever the post title. I want it to display the post title. The posts are submitted to a MySQL database and the title row is called "title". Any help is appreciated with this small question.
Update:
Here is the page itself now but it doesn't display the title. Should I open the php document and connect to my database somewhere different to it's current locations?
The Code (The only necessary piece is the beginning):

Here's the method I use (for similar things, not just title):
<?
ob_start (); // Buffer output
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title><!--TITLE--></title>
</head>
<body>
<?
$pageTitle = 'Title of Page'; // Call this in your pages' files to define the page title
?>
</body>
</html>
<?
$pageContents = ob_get_contents (); // Get all the page's HTML into a string
ob_end_clean (); // Wipe the buffer
// Replace <!--TITLE--> with $pageTitle variable contents, and print the HTML
echo str_replace ('<!--TITLE-->', $pageTitle, $pageContents);
?>
PHP usually works be executing any bits of code and printing all output directly to the browser. If you say "echo 'Some text here.';", that string will get sent the browser and is emptied from memory.
What output buffering does is say "Print all output to a buffer. Hold onto it. Don't send ANYTHING to the browser until I tell you to."
So what this does is it buffers all your pages' HTML into the buffer, then at the very end, after the tag, it uses ob_get_contents () to get the contents of the buffer (which is usually all your page's HTML source code which would have been sent the browser already) and puts that into a string.
ob_end_clean () empties the buffer and frees some memory. We don't need the source code anymore because we just stored it in $pageContents.
Then, lastly, I do a simple find & replace on your page's source code ($pageContents) for any instances of '' and replace them to whatever the $pageTitle variable was set to. Of course, it will then replace <title><!--TITLE--></title> with Your Page's Title. After that, I echo the $pageContents, just like the browser would have.
It effectively holds onto output so you can manipulate it before sending it to the browser.
Hopefully my comments are clear enough.
Look up ob_start () in the php manual ( http://php.net/ob_start ) if you want to know exactly how that works (and you should) :)
You parse the field from the database as usual.
Then let's say you put it in a variable called $title, you just
<html>
<head>
<title>Ultan.me - <?php echo htmlspecialchars($title);?></title>
</head>
EDIT:
I see your problem. You have to set $title BEFORE using it. That is, you should query the database before <title>...
header.php has the title tag set to <title>%TITLE%</title>; the "%" are important since hardly anyone types %TITLE% so u can use that for str_replace() later. then, you use output buffer like so
<?php
ob_start();
include("header.php");
$buffer=ob_get_contents();
ob_end_clean();
$buffer=str_replace("%TITLE%","NEW TITLE",$buffer);
echo $buffer;
?>
For more reference, click PHP - how to change title of the page AFTER including header.php?
What about using something like:
<?php
$page_title = "Your page tile";
include("navigation.php"); // if required
echo("<title>$page_title</title>");
?>
Move the data retrieval at the top of the script, and after that use:
<title>Ultan.me - <?php echo htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); ?></title>
You need to set the value of $title before echoing it.
Also, you should really sanitize any data before using it in queries as this is a security risk
create a new page php and add this code:
<?php
function ch_title($title){
$output = ob_get_contents();
if ( ob_get_length() > 0) { ob_end_clean(); }
$patterns = array("/<title>(.*?)<\/title>/");
$replacements = array("<title>$title</title>");
$output = preg_replace($patterns, $replacements,$output);
echo $output;
}
?>
in <head> add code: <?php require 'page.php' ?> and on each page you call the function ch_title('my title');
The problem is that $title is being referenced on line 5 before it's being assigned on line 58. Rearranging your code isn't easy, because the data is both retrieved and output at the same time. Just to test, how does something like this work?
Because you're only retrieving one row, you don't need to use a while loop, but I left it with hopes that it'll make it easier for you to relate to your current code. All I've done is removed the actual output from your data retrieval, and added variables for category and category name which are then referred to as usual later on. Also, I haven't tested this. :)
It'll be tricky to rearrange your code to make this work, but I'll try :)
So, put this at the top of your code:
<?php require_once('mysql.php'); ?>
The top of the file should look like:
<?php require_once('mysql.php'); ?>
<html>
<head>
<meta name="keywords" content="Mac user Ultan Casey TheCompuGeeks UltanKC">
<title>Ultan.me - <?php echo htmlspecialchars($title); ?> </title>
Then, create a file called mysql.php in the same directory that the file which contains the code you quoted is in.
Put this is mysql.php:
<?php
mysql_connect ('localhost', 'root', 'root');
mysql_select_db ('ultankc');
if (!isset($_GET['id']) || !is_numeric($_GET['id'])) {
die("Invalid ID specified.");
}
$id = (int)$_GET['id'];
$sql = "SELECT * FROM php_blog WHERE id='$id' LIMIT 1";
$result = mysql_query($sql) or print ("Can't select entry from table php_blog.<br />" . $sql . "<br />" . mysql_error());
$res = mysql_fetch_assoc($result);
$date = date("l F d Y", $res['timestamp']);
$title = $res['title'];
$entry = $res['entry'];
$get_categories = mysql_query("SELECT * FROM php_blog_categories WHERE `category_id` = $res['category']");
$category = mysql_fetch_array($get_categories);
?>
Well, hope that helped :)
I know this is an old post but having read this I think this solution is much simpler (though technically it solves the problem with Javascript not PHP).
<html>
<head>
<title>Ultan.me - Unset</title>
<script type="text/javascript">
function setTitle( text ) {
document.title = text;
}
</script>
<!-- other head info -->
</head>
<?php
// Make the call to the DB to get the title text. See OP post for example
$title_text = "Ultan.me - DB Title";
// Use body onload to set the title of the page
print "<body onload=\"setTitle( '$title_text' )\" >";
// Rest of your code here
print "<p>Either use php to print stuff</p>";
?>
<p>or just drop in and out of php</p>
<?php
// close the html page
print "</body></html>";
?>
Simply add $title variable before require function
<?php
$title = "Your title goes here";
require("header.php");
?>
header.php
<title><?php echo $title; ?></title>
<?php echo APP_TITLE?> - <?php echo $page_title;?>
this should work fine for you
if you want to current script filename as your title tag
include the function in your project
function setTitle($requestUri)
{
$explodeRequestUri = explode("/", $requestUri);
$currentFileName = end($explodeRequestUri);
$withoutExt = preg_replace('/\\.[^.\\s]{3,4}$/', '', $currentFileName);
$explodeCurrentFileName = explode("-", $withoutExt);
foreach ($explodeCurrentFileName as $curFileValue)
{
$fileArrayName[] = ucfirst($curFileValue);
}
echo implode(" ", $fileArrayName);
}
and in your html include the function script
and replace your title tag with this
<title>Your Project Name -
<?php setTitle($_SERVER['REQUEST_URI']); ?>
</title>
it works on php7 and above but i dont have any idea about php 5.*
Hope it helps
