PHP - String Concatenation With Php - A Newbie-question For A Little Parser With Curl

I am trying to figure out how to have an if statement in the middle of strings I am trying to concatenate. I have a from that has a address1 and address2, where address2 often does not exist. So I want to only add that line if there is actually content. I was trying something like the following, but that is giving me an error. I am pretty new to php, so I can't seem figure it out. Any help would be greatly appreciated.

Code: [Select]
"<p><strong>Address 1: </strong><br>" . $address1 . "<br>"
if ( isset($address2) ) { echo . $address2 . "<br>" }
. $city . ", " . $state . " " . $zip . "</p>"

Code: [Select]
<?php
$dom = new DOMDocument();
$dom->loadHTMLFile('http://en.wikipedia.org/wiki/Liverpool_F.C.');
$domxpath = new DOMXPath($dom);
foreach ($domxpath->query('//span[@id="Players"]/../following-sibling::table[1]//span[@class="fn"]') as $a)
{echo
"
<p>$a->textContent</p>
";
};
?>

Hello, how can I parse an XML that includes all of the $a->textContent with a tag like <player></player>?

hello dear Freaks 

 

i am currently  musing bout the portover of a python bs4 parser to php -  working with the simplehtmldom-parser / pr the DOM-selectors... (see below).

The project: for a list of meta-data of wordpress-plugins: - approx 50 plugins are of interest! but the challenge is: i want to fetch meta-data of all the existing plugins. What i subsequently want to filter out after the fetch is - those plugins that have the newest timestamp - that are updated (most) recently. It is all aobut acutality...

https://wordpress.org/plugins/participants-database ....and so on and so forth.  

https://wordpress.org/plugins/wp-job-manager
https://wordpress.org/plugins/ninja-forms
https://wordpress.org/plugins/participants-database ....and so on and so forth.
 

we have the following set of meta-data for each wordpress-plugin:

Version: 1.9.5.12 
installations: 10,000+    
WordPress Version: 5.0 or higher 
Tested up to: 5.4 PHP  
Version: 5.6 or higher

the project consits of two parts:   the looping-part: (which seems to be pretty straightforward). the parser-part: where i have some issues - see below. I'm trying to loop through an array of URLs and scrape the data below from a list of wordpress-plugins. See my loop below-

as a base i think it is good starting point to work from the following target-url: 

 plugins wordpress.org/plugins/browse/popular with 99 pages of content: cf ...
 wordpress.org/plugins/browse/popular/page/1 
wordpress.org/plugins/browse/popular/page/2
wordpress.org/plugins/browse/popular/page/99

 

the Output of text_nodes:

['Version: 1.9.5.12', 'Active installations: 10,000+', 'Tested up to: 5.6 ']  

but if we want to fetch the data of all the wordpress-plugins and subesquently sort them to show the -let us say - latest 50 updated plugins. This would be a interesting task:

 

first of all we need to fetch the urls

then we fetch the information and have to sort out the newest- the newest timestamp. Ie the plugin that updated most recently

List the 50 newest items - that are the 50 plugins that are updated recently ..

 

we have the following set
 

see here the Soup_ 

 soup = BeautifulSoup(r.content, 'html.parser')
        target = [item.get_text(strip=True, separator=" ") for item in soup.find(
            "h3", class_="screen-reader-text").find_next("ul").findAll("li")[:8]]
        head = [soup.find("h1", class_="plugin-title").text]
        new = [x for x in target if x.startswith(
            ("V", "Las", "Ac", "W", "T", "P"))]
        return head + new


with ThreadPoolExecutor(max_workers=50) as executor1:
    futures1 = [executor1.submit(parser, url) for url in allin]

for future in futures1:
    print(future.result())

 

see the formal output

what would be the best code to use to just use curl to reload a url in a loop? Like what all options do I need that would be the fastest?

Ive been using

Code: [Select]

<?php

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_close($ch);

?>

I'm trying to automate with php and the form I need to submit has a post call with hidden inputs.

How do I mimic a post call to another page with the hidden inputs using curl? The hidden inputs has to be carried over to the next page so I can continue the process though.

How do i load a page that is entirely made in javascript
i`ve tried to load  a page but its not loading it

Code: [Select]
<td valign="middle"><b id="loadingMessage">Loading...</b></td>
its keeps getting stuck at Loading
I have FOLLOWLOCATION 1


Code: [Select]
  $ch = curl_init();
    curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );
    curl_setopt( $ch, CURLOPT_URL, $url1 );
    curl_setopt( $ch, CURLOPT_COOKIEJAR, $cook );
    curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
    curl_setopt( $ch, CURLOPT_ENCODING, "" );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
    curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );    # required for https urls
    curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
    curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
    curl_setopt( $ch, CURLOPT_MAXREDIRS, 10 );
    $content = curl_exec( $ch );
    $response = curl_getinfo( $ch );
    curl_close ( $ch );

echo $content;
print_r( $response);


how do i load a page that is made in javascript with curl ?
or does it have hidden .htm files that are loading through javascript

I have a web server which contains a public site and a private site. I want to be able to test for public or private using the page title and return the appropriate header which contains a different banner, css etc.

Firstly - the syntax below seems to be incorrect because it doesnt work correctly.
More importantly how do I add all the values to an array and than iterate through it to check for a matching page title?

Code: [Select]
public function publicSite() {
if ($this->getTitle()== 'Home' || 'About Us'||'Registration' || 'Sitemap' || 'Contact Us' || 'Useful Links' || 'Feedback') {
return true;
}
return false;
}
Then later on I would have:
Code: [Select]
if ($this->publicSite()) {
require($ROOT.'interface/pages/publicheader.php');
}
else {
require($ROOT.'interface/pages/privateheader.php');
}

Thanks heaps!

Hi there, I am scratching my head for ages trying to get this to work.  I am adapting a script that simply outputs a floorplan image from a MySQL database. Only problem is that it outputs the <DIV> and all the title and formatting even if no image exists. I only want to output the <DIV> if an image exists.  Thanks in advance for any help. Charlotte


Code: [Select]
<div id="property-contact">
    <h2 id="h2-section" class="h2-section"><?php _e('Floor Plan',TS_DOMAIN) ?></h2>
    <div class="box2 clearfix">
   <?php $floor_plans_image_id =get_post_meta($post->ID, "_thumbnail_id", true);
    $myrows = $wpdb->get_results( "SELECT guid FROM wp_posts WHERE ID=".$floor_plans_image_id );

   ?>
   <a href="<?=$myrows[0]->guid?>" rel="prettyPhoto[gallery]"><img src="<?=$myrows[0]->guid?>" width="250px;"/></a>
</div><!-- end box3 -->
</div>

Im trying to do but i cannot go through can someone show me any way to ??

hi I'm a newbie in php and I came across this

Code: [Select]
if($_SERVER['REQUEST_METHOD'] == 'POST'){

and this
Code: [Select]
$_POST = $this->_params;

I know this might be a stupid question but can you please tell me what they are

Hi I'm trying to insert some information into my database but it tells me that the name is undefined how to I define it so that it works.

Here is my code
Code: [Select]
<html>
<body>

<form action="insert.php" method="post">
name: <input type="text" name="name" />
email: <input type="text" name="email" />
password: <input type="text" name="password" />

<input type="submit" />
</form>

</body>
</html>
<?php
$link = mysql_connect('localhost','test',''); 
if (!$link) { 
die('Could not connect to MySQL: ' . mysql_error()); 
} 
mysql_close($link); 

$sql="INSERT INTO emails (name,email, password)
VALUES
('$_POST[name]','$_POST[email]','$_POST[password]')";

mysql_close($con)
?>

After looking around the net and getting i feel close i though i would post and ask you all.

I am trying to add x number of names to a database each on its own row. I found some code and have edited it and i understand most of what its doing but i cannot get it to work, it just add witch ever name was last.

Here is the form code just with 3 test fields.
Quote

<form id="form1" name="form1" method="post" action="addplayer2.php">
       <p>
        <input name="player[]" type="text" id="player[]" size="15" />
      </p>
         <p>
        <input name="player[]" type="text" id="player[]" size="15" />
      </p>
         <p>
        <input name="player[]" type="text" id="player[]" size="15" />
      </p>
 <input type="submit" name="submit" id="submit" value="Submit" />
</form>


Ok this the script i found in it unedited state, i thought i would be easy to understand if you saw it before i broke it.

I tried changing the word Activity to player and the work Act to play and then changing all other referanced.
Quote

<?php
$con = mysql_connect("localhost","Application","*******");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("CpaApp", $con);

foreach($_POST['Activity'] as $row=>$Act)
{
$Activity=$Act; // why does this not have post? Or is it using the one above?
$Position=$_POST['Position'][$row];
$StartDate=$_POST['StartDate'][$row];
$EndDate=$_POST['EndDate'][$row];
}


//enter rows into database
foreach($_POST['Activity'] as $row=>$Act)
{
$Activity=mysql_real_escape_string($Act); // Same question why no $_POST? does it use the one above?
$Position=mysql_real_escape_string($_POST['Position'][$row]);
$StartDate=mysql_real_escape_string($_POST['StartDate'][$row]);
$EndDate=mysql_real_escape_string($_POST['EndDate'][$row]);
}


$involv = "INSERT INTO Involvement (Activity, Position, StartDate, EndDate)
VALUES ('.$Activity.','.$Position.','.$StartDate.','.$EndDate.')";


if (!mysql_query($involv,$con))
{
die('Error: ' . mysql_error());
}
echo "$row record added";

mysql_close($con)
?>


On filling out the fields with name lets say Paul Bill and Jack it echos that it has added x number of rows but when looking in the database it has only added the last in this case Jack.

If there is anyone willing to edit the code above so it will work with my single field i would be very great full, also if someone would answer the questions i placed in the script that would be great also.

Many thanks.

Hi, I'm REALLY new to PHP, so any help would be appreciated .  I'm trying to make a script that truncates a post after a certain amount of words (Below).  And I suppose the article would have to have $description="blahblahblah";.  My question is; how would I go about making this script actually work?  Where would I put the code and the articles? Like I said, I have less than 2 days experience with PHP, so please don't judge
Code: [Select]
// this signifies how to truncate
function myTruncate($string, $limit, $break=".", $pad="...")
{
  // return with no change if string is shorter than $limit
  if(strlen($string) <= $limit) return $string;

  // is $break present between $limit and the end of the string?
  if(false !== ($breakpoint = strpos($string, $break, $limit))) {
    if($breakpoint < strlen($string) - 1) {
      $string = substr($string, 0, $breakpoint) . $pad;
    }
  }

  return $string;
}
And the code that says when to truncate:
Code: [Select]
// replace 'xxx' with the number desired

  $shortdesc = myTruncate($description, XXX);
  echo "<p>$shortdesc</p>";

I'm just learning PHP as a first language so you'll probably see my around here quite a bit!

I'm completely baffled at why this isn't working and after about 30 minutes of frustration I decided to seek some help lol.

Code: [Select]
require '/opt/lampp/htdocs/PHP/Chapter 3/scripts/app_config.php';
//database connection code

if (mysql_connect($db_host, $username, $password) != false) {
mysql_select_db("db_name");
echo "MySQL Database Selected";
}
else {
echo "Error connecting to database";
}
app_config.php
Code: [Select]
<php
// Database Connection Constants

$db_host = "";
$username = "";
$password = "";
$db_name = "chp3";
?>
results:
Notice: Undefined variable: db_host in /opt/lampp/htdocs/PHP/Chapter 3/scripts/connect.php on line 6

Notice: Undefined variable: username in /opt/lampp/htdocs/PHP/Chapter 3/scripts/connect.php on line 6

Notice: Undefined variable: password in /opt/lampp/htdocs/PHP/Chapter 3/scripts/connect.php on line 6


Any help is appreciated.

Hello, I'm sorry, I know nothing about php programming but need some help - I'm sure this will be a simple question! 

I have created a Formidable form on Wordpress (form is named BookingTest).  It has a drop down box on (called dropdown) that has a list of numbers that requires a unique value.  The plugin designers have shared some code that is supposed to remove used values from the drop down box but it's not working - I don't know if I've put it in the right place or if I need to edit it or anything like that.  

This is there documentation: https://formidableforms.com/knowledgebase/frm_setup_new_fields_vars/?fbclid=IwAR1Zj1jWo6iqdR4Cjq8MGpTLRW01XToPR7vp_2oN4XEmQ81SLAW-sbtbYKU#kb-remove-used-options

I have pasted this code in it's entirety to a Code Snippets plugin but I still get all the values appear.  

Do I need to amend it to refer to my form explicitly?  How is this filter called?  Do I need to add an action?!

Really confused :(

Thank you!
