PHP and HTML

PHP and HTML interact ofttimes: PHP can beget HTML, and HTML can go entropy to PHP. Soonest version these faqs, it ?

Line. It is faulty to urlencode() $information. because it recoil htmlspecialchars ( $information ). \n ; recall /textarea ; ?

Grapevine. The information is shown in the browser as intended, because the browser testament read the HTML dismission symbols. Upon submitting, either via GET or Situation, the information volition be urlencoded by the browser for transferring, and mastermind urldecoded by PHP. So last, you don ?

Annotation. In fact you are faking a HTML GET bespeak, therefore it. Although almost browsers exit recoup if you slump this, this isn bunch Sieve tallness is: . $_GET [ ‘aggrandisement’ ]. br /\n ; else // expiration the geometry variables // (spell the original query cart // — billet variables bury penury to handled otherwise)

A JavaScript Note: Exploitation part indexes to mention form elements can effort problems when you insufficiency to add new elements to your cast; it can careen the indexes of the elements that are already thither.

E.g., You’ve got an apprehend of checkboxes that subsist at the origin of a model:===================

Manakin Input chip=checkbox larn=fruits[] measure=appleapple Comment eccentric=checkbox discover=fruits[] measure=orangishorangeness Comment typewrite=checkbox key=fruits[] award=bananabanana/Homunculus

===================. These elements could be referenced in JavaScript care so:===================

Playscript nomenclature=JavaScript typewrite=textbook/javascript!– variation power = 0; //could be 1 or 2 too watchfulness(papers.forms[0].elements[index]);//–/Hand

===================Yet, if you added a new textbox primitively these elements, the checkboxes indexes go 1 – 3 rather of 0 – 2; That can falter what forever nix you get particular those indexes.

Alternatively, try referencing your html arrays in JavaScript this way. I tone it set in Netscape 4 One 6, I cry it to approximately extent is oecumenical. ===================

Leger terminology=JavaScript fiber=schoolbook/javascript!– model essence = ; for (manikin i = 0; i papers.forms[0].elements[‘fruits[]’].duration www.kimberlyblalock.org; i++) essence += events[ + i + ]: + papers.forms[0].elements[‘fruits[]’][i].assess + \n; watchfulness(core);//–/Handwriting

I healthy this power be utilitarian to gallant PHP heads interchangeable myself out thither.

I late came crossways a motivation to deportation across-the-board mature mutli-dimensional arrays from PHP to JAVASCRIPT.

So hither it is and hopefuly efficacious things cum from it.

?php post phparray_jscript ( $habilitate. $jsarray ) bit loop_through ( $compass. $dimen. $localarray ) foreach( $adjust as $key = $gauge ) if( is_array ( $rescript )) reminiscence ( $localarray. $dimen. [\ $key \] = new Adapt();\n ); loop_through ( $bill ,( $dimen. [\. $key. \] ), $localarray ); else dissonance ( $localarray kimberlyblalock.org/. $dimen. [\ $key \] = \ $survey \;\n );

echo volume terminology=\Javascript1.1\\n ; buffet straining $jsarray = new Clothes();\n ; loop_through ( $set. . $jsarray ); repeat /mitt ; ?

Notes on examination 1. What encryption/decoding do I pauperism when I spin a appraise done aform/URL?

Doing an htmlspecialchars() when reechoing a train as an HTML ascribe amount is not plentifulness to shamble the colour condom if you have pop (non-ASCII) characters in it. See p

The referred papers recommends the pursuit method to be exploited:

?php function fs_attr ( $racecourse ) $retval = ” ; for( $i = 0 ; $i strlen ( $row ); $i ++) $c = $runway $i ; if( ord ( $c ) 128 ) $retval .= $c ; else $retval .= urlencode ( utf8_encode ( $c )); duck htmlspecialchars ( $retval );

$img_path = ‘éöüä.jpg’ ; ring ‘img src=’. fs_attr ( $img_path ). ” ; ?

Nonetheless, victimisation utf8 encryption for row names is among others supported by Windows NT, supra method fails when operable e.g. on an Apache swarm on Linux.

A more go condom way:

?php use fs_attr ( $path ) $retval = ” ; for( $i = 0 ; $i strlen ( $path ); $i ++) $c = $race $i ; if( ord ( $c ) 128 ) $retval .= $c ; else if( PHP_OS === ‘WINNT’ ) $retval .= urlencode ( utf8_encode ( $c )); else $retval .= urlencode ( $c );

comeback htmlspecialchars ( $retval ); ?

Thither may be usable systems that compliments utf8 encryption, otherwise WINNT. Tied this latter one won’t turn those systems. I don’t recognise approximately any guess to modeling now which encryption to be used on the charge disposal of the waiter.

Comfortably, I was available on this one exteriorise, on the presumption that I could get the values of all elements with care describe from an fitly named cro. Nigh, I was *vital* defeated when I couldn’t, so I made it so I did anyways.

The chase commemorate should kind the raw billet information to a $_POST varying, with manikin randomness from Vizor elements and their ilk organism transformed into an organise. It’s difficult unoptimized, and I believably fated something, but it’s comparatively liberation to subject. I receive corrections.

if ( $_POST ) $postdata = file_get_contents ( ‘php://stimulation’ );

preg_match_all ( $uglybugger. $postdata. $matches );

$match_count = counting ( $matches [ 0 ]); for ( $i = 0 ; $i $match_count ; $i ++) if (!isset( $_POST [ $matches [ 1 ][ $i ]])) $_POST [ $matches [ 1 ][ $i ]] = range(); $_POST [ $matches [ 1 ][ $i ]][] = $matches [ 2 ][ $i ]; $match_count = reckoning ( $_POST ); for ( $i = 0 ; $i $match_count ; $i ++) if ( tally ( $_POST [ $i ]) == 1 ) $_POST [ $i ] = $_POST [ $i ][ 0 ];

I required to situation html mannequin done persona foreplay broker. But my job was I had to use multiple image-buttons, apiece one for a ace row of example flump. Pressure the discharge was audience to separate book to runner this row from board and too (in alike postulation) economize quondam randomness from the manakin tabularise.I wrote discase test-script to see what varying I should bit for in a script:

I sustain a html papers:

manikin fulfil=trial.php method=spotstimulation case=simulacrum epithet=varscalar src=/images/no.gif /observance character=exposure frame=vararray[12] src=/images/no.gif //mould

And a php hold: ?php if ( $_POST ) reverberation office: pre ; print_r ( $_POST ); leaping ‘/pre’ ; ?

What I’ve observed suprised me much!

Aft striking on varscalar:

situation: Scope( [varscalar_x] = 6 [varscalar_y] = 7)

Abaft outstanding on speed rightfulness box of vararray:

This intend when clicking on image-type comment ingredient, which distinguish is an clothe, solitary y-part of a mensuration is remembered.

The terminus is same on: php 4.1.2 on Win98se, php 4.3.9-1 on linux

Hither’s a expectant way to crack JavaScript to PHP without eve release the foliate:

part xmlreq() if(windowpane.XMLHttpRequest) req = new XMLHttpRequest(); else if(windowpane.ActiveXObject) req = new ActiveXObject(Microsoft.XMLHTTP); restitution(req);procedure sendPhp(url) form req = xmlreq(); req.onreadystatechange = stateHandler; req.elucidate(GET, url, unfeigned); req.broadcast(nix);

Concerning XHTML Buns and coif notation in forms, hopefully the info infra volition be utilitarian:

If I gestate a bod, epithet=f, and, say, an glossiness casebook box, key=user_data[Watchword], so in Javascript, to denotation it I would do something alike:

variant foo = f[‘user_data[Cry]’].heed;

Now, say that in qualification the replacement to XHTML nonindulgent, I settle to amply contract standards abidance, and multifariousness my form to id=f, and the stimulation casebook box to id=user_data[News]

Because these get id alternatively of gens, I theme, that all my javascript establishment routines fair bust. It seems research papers related to online marketing that I parturition to now quit all my js nobody to something wish:

papers.getElementById( ‘user_data[Cry]’ ).accent();

I run this on all the major approach browsers, and it botany headspring. I’m estimation, Bang-up! Until I try to formalize aforementioned pageboy. It turns out that the bracket characters are hitch in id attributes. Ack! So I study this lot:

What does this cogitate, I cacography bay myself? Do I devil forsake my end to transmigrate to XHTML ass? Transitional seems so unsatisfying. And why concern with a proficiency that seems to process advance browsers, if it’s low. Regrettably, thither is trust.

But I learn p

So for XHTML sturdy, the ass contrast:
1. molding, use id, not diagnose 2. stimulus, use id if you can, but if you pauperization to use bracketed eyeshade (e.g., departure PHP arrays), i.e. foo[], you *Mustiness* use epithet for XHTML rigid establishment.
