Title: Combine processor not replacing Last modified: May 22, 2017 --- # Combine processor not replacing * Resolved [Avf](https://wordpress.org/support/users/avf/) * (@avf) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/) * Hello and thanks for this great plugin. My question is why when I use the combine processor, the result is the same name of the variable, not the contents? When inserting {po[1] full_html} as per instructions, it shows exactly the same {po[ 1] full_html} as output, and not the contents of po[1] full_html.

Is it the latest? * Please export your pipe and upload it onto a share host (such as [Dropbox](https://www.dropbox.com/referrals)) then provide me the link! I will try to check how it works on my demo site! * Best Regards! * Thread Starter [Avf](https://wordpress.org/support/users/avf/) * (@avf) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/#post-9161200) * WP version 4.7.5 WP-Pipes version 1.25. I created a test pipe, you can download it from [https://1drv.ms/u/s!Aiveo2dI6XKtoWZ9LKi60ugRj4Aw](https://1drv.ms/u/s!Aiveo2dI6XKtoWZ9LKi60ugRj4Aw). I’ve never got the combine processor to work, for some reason (maybe a php mod missing from my server?). You can check the feed created by the pipe at [https://www.fontoura.com/feeds/testing.rss](https://www.fontoura.com/feeds/testing.rss) and notice the description is not correct, as below: * ``` Auditores fiscais entram em greve e fazem operação padrão nas aduanas https://www.fontoura.com/noticias/fontes/agencia-brasil/auditores-fiscais-entram-em-greve-e-fazem-operacao-padrao-nas-aduanas/ {po[0] html}: {pi[1] html} {po[1] introtext} 25458156c5222d74956599335c97200e https://www.fontoura.com/noticias/fontes/agencia-brasil/auditores-fiscais-entram-em-greve-e-fazem-operacao-padrao-nas-aduanas/ ``` * Thanks again.

Please watch this [https://www.screencast.com/t/mCfwGMQaiY](https://www.screencast.com/t/mCfwGMQaiY) * I only removed {pi[1] html} in Combine processor because that tag is not usable. You could only use tags with the output fields of Source add-on and other processors.{ pi[1] html} is the input field, not output. * Please check **WPPipes Requirements** in the settings page of WPPipes on your site! * Thread Starter [Avf](https://wordpress.org/support/users/avf/) * (@avf) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/#post-9163515) * Thanks for your reply. That’s very interesting, even without pi it doesn’t work. All requirements are satisfied, however we are running php 7. Can you please provide more information on the technical side of this processor, so we can know where to debug? Maybe the php file where the processor is. I’m thinking it could be an opcache issue. * Plugin Contributor [Tung Pham](https://wordpress.org/support/users/phamtungpth/) * (@phamtungpth) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/#post-9166476) * Hi, * The Combine processor’s code is located at YOUR_PATH_SITE/wp-content/plugins/ wp-pipes/plugins/processors/combine/combine.php file. * Best Regards! * Thread Starter [Avf](https://wordpress.org/support/users/avf/) * (@avf) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/#post-9168185) * Thanks! Ok, debugging that file, I get the following error for each tag that should be replaced: * “Notice: Array to string conversion in /wp-content/plugins/wp-pipes/plugins/processors/ combine/combine.php on line 37” * Line 37 is `if(isset($data->no_need['op'][$result[0]]->$seperate_array[1])){` * Any idea on what’s going on? * Thread Starter [Avf](https://wordpress.org/support/users/avf/) * (@avf) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/#post-9168812) * It seems this code * ``` preg_match('/(?<=\[).*?(?=\])/i', $seperate_array[0], $result); if(isset($data->no_need['op'][$result[0]]->$seperate_array[1])){ $inputs[$matches[0][$key]] = $data->no_need['op'][$result[0]]->$seperate_array[1]; } ``` * is not compatible with php7. - This reply was modified 8 years, 11 months ago by [Avf](https://wordpress.org/support/users/avf/). * Plugin Contributor [Tung Pham](https://wordpress.org/support/users/phamtungpth/) * (@phamtungpth) * [8 years, 11 months ago](https://wordpress.org/support/topic/combine-processor-not-replacing/#post-9178965) * Hi, * Thank you for informing! * I just release new version of WPPipes.
