Form misses field from time to time

[starflix]

Hello,

I’ve encountered this problem recently, that my form for some reason misses one very important field. I have no idea what can cause this bug, I tried to find what triggers this bug but had no success at all.

So my form has this input field which is hidden, when user fills dynamically created fields, all information goes into that field, which is then is processed at PHP and returned as an output. I would really appreciate any kind of help! Thank you in advance

Here are the codes:
JS

	function formString() {
		const pageTitles = Array.prototype.slice.call(document.querySelectorAll('.page-title'), 0).map(x => {
			return x.innerText; //make nodelist to array, then map over it to get names
		});

		let finalString = "";

		pageTitles.forEach(function(page) {
			const x = page.split(' → ');
			const pageClass = x[x.length -1].split(' ').join('-');

			let content = document.querySelector('.' + pageClass + ' .page-content-text_textarea').value.replace(new RegExp('\r?\n','g'), '[[newline]]');
			let comments = document.querySelector('.' + pageClass + ' .page-comment-text_textarea').value.replace(new RegExp('\r?\n','g'), '[[newline]]');
			let title = page;

			if(title === "") { title = "Teksto nera"; }
			if(content === "") { content = "Teksto nera"; }
			if(comments === "") { comments = "Teksto nera"; }

			finalString += title + '~~~' + content + '###' + comments + ';;;';
		});

		console.log(finalString);
		document.querySelector('input[name="quform_3_164"]').value = finalString;
	}

PHP

add_filter('quform_get_value_html_3_164', function ($value) {
	$output = '';
	$counter = 0;

	$value = explode(';;;', $value);

	if(count($value)) {
		foreach($value as $blocks) {
			$blocks = explode('~~~', $blocks);

			if(count($blocks)) {

				if($counter % 2 == 1) {
					$output .= '<div style="background-color: #f6f6f6; padding: 50px 25px;">';
					$output .= '<h2 style="font-size: 32px;text-decoration: underline;">' . esc_html($blocks[0]) . '</h2>';

					foreach(array_slice($blocks, 1) as $blocksChild) {
						$blocksChild = explode('###', $blocksChild);

            $blockOne = explode("[[newline]]", $blocksChild[0]);
            $blockTwo = explode("[[newline]]", $blocksChild[1]);

						if(count($blocksChild)) {
							$output .= '<h3>Turinys</h3>';
              forEach($blockOne as $paragraph) {
                $output .= '<p>' . esc_html($paragraph) . '</p>';
              }
							$output .= '<h3>Komentarai</h3>';
              forEach($blockTwo as $paragraph) {
                $output .= '<p>' . esc_html($paragraph) . '</p>';
              }
						}
					}
					$output .= '</div>';
				} else {
					$output .= '<div style="background-color: #fcfcfc; padding: 50px 25px;">';
					$output .= '<h2 style="font-size: 32px;text-decoration: underline;">' . esc_html($blocks[0]) . '</h2>';

					foreach(array_slice($blocks, 1) as $blocksChild) {
            $blocksChild = explode('###', $blocksChild);

            $blockOne = explode("[[newline]]", $blocksChild[0]);
            $blockTwo = explode("[[newline]]", $blocksChild[1]);

						if(count($blocksChild)) {
							$output .= '<h3>Turinys</h3>';
              forEach($blockOne as $paragraph) {
                $output .= '<p>' . esc_html($paragraph) . '</p>';
              }
							$output .= '<h3>Komentarai</h3>';
              forEach($blockTwo as $paragraph) {
                $output .= '<p>' . esc_html($paragraph) . '</p>';
              }
						}
					}
					$output .= '</div>';
				}
			}
			$counter++;
		}
	}

	return $output;
});

Hello.

I inserted this field to check what information I get. It seems its not the case in this problem. Because client just filled the form and I see he is using firefox 52 (Mozilla/5.0 (Windows NT 5.1; rv:52.0) Gecko/20100101 Firefox/52.0). I checked the const usability and it seems that it shouldn’t be a problem on this version. Do you can any other suggestions where problem might be laying?

Thank you in advance

It seems I accidentally found the problem. The problem was that the person would fill one of the fields and use some kind of symbol, for example question mark. This would ruin everything because later in the form those fields are used as classNames..

Thank you for help!
