How to convert an jpg image to base64 with php in Wordpress?

0 votes
710 views

I am trying to convert an jpg image on my Wordpress blog to base64. I use this php code but it's not working:

$thePostThumb = get_the_post_thumbnail($postId, array(150,150));
background-image: url(\'data:image/jpg;base64,' . base64_encode($thePostThumb) . '\');

I have also tried this method:

$type = pathinfo(get_the_post_thumbnail_url($postId, array(150,150)), PATHINFO_EXTENSION);
$data = file_get_contents(get_the_post_thumbnail_url($postId, array(150,150));
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data)

I know the thumb image is being retrieved, just can't get it working. Anyone know what might be going on.

Use this code this must be work, just tested locally:

$image = get_the_post_thumbnail_url($postID, array(150,150));
$ext = pathinfo($image, PATHINFO_EXTENSION);
echo 'data:image/' . $ext . ';base64,' . base64_encode(file_get_contents($image));

How to positioning image banner on a wordpress site?

In my wordpress site I have a picture in header section. On a full screen it looks ok but on mobile and when minimized the picture is on the left of the page. I would like it to be on the right. I thought that maybe I had to use CSS to reposition it so I did the following:
.widget-header img { float: left; } to .widget-header img { float: right; }
in hopes that it would work. However nothing seems to have changed. Can anybody help me how I fix this problem?

How I can get started working with PHP/MySQL inside of the WordPress app?

I have moderate level PHP programming skills. I am also interested in merging those skills inside of the WordPress app. With their advanced responsive design themes and many other functions it seems like a good idea. I have tried loading some PHP plug-ins in WP – but I don't seem to get them to do more than basics.

Can anybody help me on how I can get started working with PHP/MySQL inside of the WordPress app?

How to export certain fields from PHP to CSV in Wordpress?

I am trying to export certain data from my PHP form to CSV. I can echo out to screen during testing and I can also export to CSV the static test data (stored in the $contents array) you see below. But I am stuck trying to export the certain fields that I only need to export.
This is my code

// How do I get this info into the CSV?
/*foreach ( $entries as $entry ) :  
    echo $entry['2'];
    echo $entry['3'];
    echo $entry['6'];
endforeach;*/

$csv_headers = [
    'Organisation Name',
    'Registered Charity Number',
    'Address',
    'Phone',
];

$contents = [
  [2014, 6, '1st half', 'roland@fsjinvestor.com', 0, 0],
  [2014, 6, '1st half', 'steve@neocodesoftware.com', 0, 0],
  [2014, 6, '1st half', 'susanne@casamanager.com', 0, 0],
  [2014, 6, '1st half', 'tim', 0, 0]
];

fputcsv($output_handle, $csv_headers);

foreach ( $contents as $content) :
    fputcsv($output_handle, $content);
endforeach;

How to add variable inside an embedding gravity forms in Wordpress?

I need to add a variable inside an array of an embedding gravity forms to populate 2 hidden fields: email and jobname.

Here is my code:

<?php 

    $email = get_field( "email_application" );
    $jobtitle = get_the_title();

    gravity_form( 5, false, false, false, array('email'=>'echo "$email";','jobname'=>'print "$jobtitle";'), false); 
?>

I know that echo, print or just the variable doesn't work as it show like this in my code:

<input name="input_6" id="input_5_6" type="hidden" value="print $jobtitle" class="gform_hidden" aria-invalid="false">

and

<input name="input_5" id="input_5_5" type="hidden" value="echo "$email";" class="gform_hidden" aria-invalid="false">

Instead I should get:

<input name="input_6" id="input_5_6" type="hidden" value="My job title" class="gform_hidden" aria-invalid="false">

and

<input name="input_5" id="input_5_5" type="hidden" value="myaddress@email.com" class="gform_hidden" aria-invalid="false">

Can someone could point me in the right direction.

Thank you.
