    rewrite rule for no page extension

    in Apache HTTP Server

    Posted

    I'm basically after the rewrite rules to omit the .php extension of the URL, with and without the trailing slash, so for example:

     

    localhost/page should redirect to localhost/page/

     

    localhost/page/ should redirect to localhost/page.php

     

    Currently I have this code:

     

    RewriteCond %{REQUEST_FILENAME}\.php -f

    RewriteRule ^(.*)$ $1.php

    RewriteRule ^(.*)/$ $1.php

     

    It does not seem to work for the URL with the trailing slash.

    Xpath help

    in PHP Coding Help

    Posted

    Hi Salathe,

     

    Basically the most recent code I posted is meant to grab all links (with a class value of 'listinglink') from a given page.

     

    I now want to run the code from my original post upon each of those links. So basically it's going to go into each of those links, find the required <P> tag and output it's data underneath the link.

     

    So a sample output would be:

     

    Link 1

    P tag content

     

    Link 2

    P tag content

     

    ...and so on.

     

    I tried using another curl() within the foreach loop but it doesn't seem to work.

     

    P.S. thanks for the helpful tip on the foreach loop!

    Xpath help

    salathe,

     

    Perhaps you can help me out with my final xpath query -

     

    I've created a scrape script which fetches all links on a page:

     

    $dom = new DOMDocument();

@$dom->loadHTML($html);

$xpath = new DOMXPath($dom);

$links = $xpath->query("//a[@class='listinglink']");

$i=0;

foreach($links as $item)
{
$href = $links->item($i);
$url = $href->getAttribute('href');
echo '<a href="'.$url.'">'.$url.'</a><br/>';
$i++
}

     

    I now need to extend this further - it needs to go in to each link and perform the xpath query from my original post. Do you have any idea how I can do this?

    Xpath help

    Basically I generated an XPath query that finds and outputs a <P> tag from a given page.

     

    The problem I am having is that this <P> tag contains <BR> tags within it's content. For example:

     

    <p>

    100 New Drive

    <br>

    New Town

    <br>

    Manchester

    <br>

    M1 AAA

    </p>

     

     
$address = $xpath->evaluate("/html/body/table/tr[5]/td[4]/p");

echo $address->item(0)->nodeValue;

     

    This outputs:

     

    100 New DriveNew TownManchesterM1 AAA

     

    Ideally I want the <P> tag to be created into an array which is split up upon each <BR> tag. I can then put the data from this array into their own fields in the database.

     

    Anybody got any suggestions on how to do this?

    I now need to extend this further - it needs to go in to each link and get the content of a particular <p> tag on the page. So for example the page output should be as follows:

     

    Link 1

    P tag content

     

    Link 2

    P tag content

     

    ...and so on. The Xpath of the P element I need is "/html/body/form/center/table/tbody/tr[5]/td[4]/table/tbody/tr[3]/td/p"

     

    Can anyone assist me with this?

    Multiple forms on the page and validation

    in PHP Coding Help

    Posted

    Basically on my page I have 3 identical forms, for example:

     

     
<form method="post" action="">
<input type="text" name="name" value="<?php echo isset($_POST['name']) ? $_POST['name'] : null ?>" />
<input type="text" name="email" value="<?php echo isset($_POST['email']) ? $_POST['email'] : null ?>" />
<input type="hidden" name="form1" />
</form>

     

    The hidden variable at the end helps me identify which form was submitted.

     

    I've implemented validation and all is fine, apart from one thing. Whenever a form is returned back with validation errors, the matching fields on the other forms also get populated. Obviously this is because they all share the same 'name' attribute, but I have a requirement to keep the same names across all forms.

     

    I could of course extend the isset() check to also check for the hidden field, but this creates too much replication.

     

    Anybody have an elegant solution to this slight problem?

    Getting list of product reviews from the database

    in PHP Coding Help

    Posted

    Here, I managed to figure this out for myself:

     

    Controller:

     

    $query="SELECT name, location, comments, date FROM reviews WHERE prod_id='$prod_id'";
$results=mysql_query($query);
$numrows=mysql_num_rows($results);

while($row=mysql_fetch_assoc($results))
{
  $name[]=$row['name'];
  $loc[]=$row['location'];
  $com[]=$row['comments'];
  $date[]=$row['date'];
}

     

    View:

     

     
for($i=0; $i<$numrows; $i++)
{
echo $name[$i];
echo $loc[$i];
echo $com[$i];
echo $date[$i];
}

     

    I cannot beleive nobody here was able to tell me this, it would have saved me a lot of time.

    Getting list of product reviews from the database

    Not yet. Basically this is how it should work:

     

    Controller:

     

    -Run the query

    -Get the resultset

    -Put the resultset into an array

     

    View:

     

    -Loop through the array and output the data

     

    Ideally I want to assign friendly variables to the $row array so they can be easily referenced in the view, e.g. $name instead of $row['name'].

     

    Surely someone must have a solution to this simple scenario.

    Getting list of product reviews from the database

    I'm trying to output the list of product reviews from a table but I'm a bit stumped at the moment.

     

    Table Reviews:

     

    id

    prod_id

    comments

    name

    location

    date

     

    Obviously a product can have more than one review. I check that $prod_id matches prod_id field in the Reviews table.

     

    Here is the code I have at the moment:

     

    $query="SELECT * FROM reviews WHERE prod_id='$prod_id'";
$results=mysql_query($query);
$numrows=mysql_num_rows($results);
$row=mysql_fetch_assoc($results);

     

    This code is in my controller file. So in my view file I need to output this data but I'm not sure if I should be using a while() loop or a foreach loop(). Ideally I would like to do all the processing in the controller file and then be able to loop through the results in my view file.

    contact form - output to page and email

    in PHP Coding Help

    Cheers teamatomic.

     

    Seems good but I'd rather not do it that way to be honest, the code I provided was a simplified version - my full code has around 15-20 fields and not all are mandatory. So I've got several isset() checks to set the $message elements - these checks would have to be replicated for my $content variable if I use the method you have suggested...

    contact form - output to page and email

    in PHP Coding Help

    Posted

    I have the following in my controller:

     

    $message['name'] = htmlentities(strip_tags(trim($_POST['name'])));

$message['email'] = htmlentities(strip_tags(trim($_POST['email'])));

$to = "info@mywebsite.com";
$subject = "Website Enquiry";
$content = html_entity_decode(implode("\n\n", $message));
$content.= "\n\nIP Address: ".$_SERVER['REMOTE_ADDR'];
$headers = "From: ".strip_tags(trim($_POST['name']))." <".strip_tags(trim($_POST['email'])).">";
@mail($to,$subject,$content,$headers);

     

    And the following in my view:

     

    echo '<tr><th><b>Name: </b></th><td>'.$message['name'].'</td></tr>';

echo '<tr><th><b>Email Address: </b></th><td>'.$message['email'].'</td></tr>';

     

    This works as expected - the POST data is output to the page and is also sent in the email. However the email does not contain the field labels, for example 'Name: ' and 'Email Address: '.

     

    This is obviously because I don't include the labels in their respective $message[] elements, as I need to enclose these in HTML tags in the view. I don't intend to include any HTML code in my controller, so does anyone have  any idea how I can satisfy both requirements?
