Hello everyone, i have created a html form and a button. Javascript reacts to the button click sends the html values to functions.php and there i have a function to insert into the wordpress database. Every field is working and is being inserted into the database but i have some problems to upload and save a image file with these steps. Iam not using a html form i wanted to go the javascript way. Is there any option/solution to insert an image file as blob into mysql using php without form submit just via javascript ajax ? Thanks and best regards, Atilla

Hello & Thanks; Here is a ' mini-Tutorial: moving text to & from <textarea> & <pre> ' http://vmars.us/ShowMe/Tutorial-Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore-RO-VM.html I'll also put code here for safekeeping : <!DOCTYPE html> <html> <head> <!-- https://www.freeformatter.com/html-validator.html http://vmars.us/ShowMe/Tutorial-Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore-RO-VM.html --> <title id="titleId"></title> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta charset="UTF-8"> <style> </style> </head> <body onload="documentURL() , onloadRestoreTextarea()" > <br> <button onclick="saveAs(filename, allHtml)">Save This Page</button> <br><br> <div id="inlineDiv" style="display: inline-block;"> <div style="border-style: solid; align-text: center; border-width: 1px; display: inline-block;"> <button onclick="sendToConcoleLog ()">sendToConcoleLog</button> <br><br> <textarea id="toConsoleLogId" rows="4" cols="12">:</textarea> </div> <div style="border-style: solid; align-text: center; border-width: 1px; display: inline-block;"> <button onclick="saveItAll()">Copy this into PRE</button> <br> <textarea class="copyFrom" rows="4" cols="12"></textarea> </div> <div style="border-style: solid; align-text: center; border-width: 1px; display: inline-block;"> <button onclick="restoreItAll()">Restore this from Pre</button> <br> <pre contenteditable="true" class="pasteInto" ></pre> </div> </div> <!-- id="inlineBlock"> --> <div style="border-style: dotted; align-text: center; border-width: 1px;"> <pre> Thought I would make a turorial so I remember what I learned from you all , and to pass on your wisdom. Hope this helps someone :) Try this: ------------------------------------------------------------------------------------------------------------------------ 1) Type something into "Copy this into Pre" textarea box . Then click "Copy this into Pre" Button . Text is copied into "Restore this from Pre" "pre area ' . And "Copy this into Pre" textarea box , is Cleared . Study This : function saveItAll() ------------------------------------------------------------------------------------------------------------------------ 2) The click on "Restore this from Pre" Button , Text is copied from "Restore this from Pre" area into "Copy this into Pre" area . And "Restore this from Pre" area , is Cleared . Study This: function restoreItAll() ------------------------------------------------------------------------------------------------------------------------ 3) Now Type something into "Copy this into Pre" textarea box Again . Then click "Copy this into Pre" Button . Text is copied into "Restore this from Pre" pre area . And "Copy this into Pre" textarea box , is Cleared . But this time , click the "Save This Page" Button . Study This: function saveAs(filename, allHtml) This .html page will be saved in your Browser's download area . Since the "Restore this from Pre" pre area , is coded as contenteditable="true" , the downloaded page will save the "pre area" text as innerHTML . A nifty feature of 'contenteditable' is that upon opening the saved-page the content of "pre area" is now " hardCoded " into page . Study This: function onloadRestoreTextarea() ------------------------------------------------------------------------------------------------------------------------ See code : So in the ' body ' tag we have : "onloadRestoreTextarea()" which runs the " function onloadRestoreTextarea() " code , when page is loaded . Which copies text from "pre area" to " textarea" box . Also at ' body onload="documentURL() ' page load time: The function: function documentURL() is run , which copies ' this .html ' file's address into the ' title ' tag . BTW: for example (see code) and note that : IF you want to copy what’s typed in the box use .value . console.log(toConsoleLogId.value); IF you want what was hardcoded into the text box’s HTML , use .innerHTML . console.log(toConsoleLogId.innerHTML); Hope this helps someone.... http://vmars.us/ShowMe/Tutorial-Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore-RO-VM.html </pre> </div> <script> var copyFromVar = "one"; function saveItAll() { var blankVar = ""; var fromList; // = document.getElementsByClassName("copyFrom"); var intoList; // = document.getElementsByClassName("pasteInto"); fromList = document.getElementsByClassName("copyFrom"); intoList = document.getElementsByClassName("pasteInto"); for (var i = 0; i < fromList.length; i++) { copyFromVar = fromList[i].value ; intoList[i].innerHTML = copyFromVar; fromList[i].innerHTML = blankVar; fromList[i].value = blankVar; } }// </script> <script> var copyFromVarTwo = "two"; function restoreItAll() { var blankVar = ""; var fromListTwo; // = document.getElementsByClassName("copyFrom"); var intoListTwo; // = document.getElementsByClassName("pasteInto"); intoListTwo = document.getElementsByClassName("copyFrom"); fromListTwo = document.getElementsByClassName("pasteInto"); for (var i = 0; i < fromListTwo.length; i++) { copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; fromListTwo[i].innerHTML = blankVar; fromListTwo[i].value = blankVar; } } </script> <script> var copyFromVarOnload = "three"; function onloadRestoreTextarea() { var fromListTwo; // = document.getElementsByClassName("copyFrom"); var intoListTwo; // = document.getElementsByClassName("pasteInto"); var blankVar = ""; intoListTwo = document.getElementsByClassName("copyFrom"); fromListTwo = document.getElementsByClassName("pasteInto"); for (var i = 0; i < fromListTwo.length; i++) { copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; fromListTwo[i].innerHTML = blankVar; fromListTwo[i].value = blankVar; } } // reloadTextarea </script> <script> function sendToConcoleLog() { var var01 = toConsoleLogId.value; console.log(var01); // alert(var01); var var01 = toConsoleLogId.innerHTML; console.log("If nothing after : Then no nothing was typed into this textarea => " + var01); alert("If nothing after : Then no nothing was typed into this textarea => " + var01); console.log(toConsoleLogId.value); console.log(toConsoleLogId.innerHTML); /* should be console.log(toConsoleLogId.value); if you want what’s typed in the box, or console.log(toConsoleLogId.innerHTML); if you want what was hardcoded into the text box’s HTML. */ } </script> <script> var filename = ""; function documentURL() { document_URL = document.URL; document.getElementById("titleId").innerHTML = document_URL; } </script> <script> var filename = "Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore.html"; var allHtml = document.documentElement.outerHTML; function saveAs(filename, allHtml) { allHtml = document.documentElement.outerHTML; var blob = new Blob([allHtml], {type: 'text/csv'}); if(window.navigator.msSaveOrOpenBlob) { window.navigator.msSaveBlob(blob, filename); } else{ var elem = window.document.createElement('a'); elem.href = window.URL.createObjectURL(blob); elem.download = filename; document.body.appendChild(elem); elem.click(); document.body.removeChild(elem); } } </script> </body> </html>

UPDATE: Please skip to Post #11 (where I've re-started the post with, "UPDATE: Restarting question/post here...") Is it (reasonably) possible to autoscroll a text (txt) blob during the playback of a video on a page, and if so then how? What I'm wanting to accomplish is very similar to what SoundHound does with audio files and lyrics; while the audio file plays the synchronized lyrics scroll by in a frame. For example, I have a video 10 minutes long that I will play on a web page. I have a txt file with short lines of data.I can manipulate the txt file however needed to make this process work. Each line of text has a time stamp (and I can place the time stamp wherever in the line I want or need it placed). The times (timestamped lines) are not in even time intervals (but I can make the intervals even by placing in filler lines if needed). Most likely I'll have one line of text for every second (and I can even force it to be one line/row per second if it makes it easier). The text lines vary in length (but if really needed I could make them the same length, so it might be possible to scroll by byte range). [*]On my page: I will have the video playing. Below the video I will have the txt blob displaying in a scrolling field. [*]I would like the text blob to scroll automatically in synchornization with the video. If the user speeds up or slows down the video or jumps to a new place (forward or back) in the video, the blob needs to remain in sync. When the video is paused then the blob needs to stop scrolling. Is this something reasonably do-able? If so, can someone point me to or provide an example? (I'm a noob at this, but trainable.) Thanks in advance, Andrew -
when people upload image or video to my site, do i store them in any special type in phpmyadmin? are you supposed to use BLOB? What is BLOB? Which of them do i use? I would guess they can store different amount of data, how much do each of them store?
