I was seeking a simple way to refresh my selections and checkboxes. I figured out a way to handle it quite easily using a combination of php and javascript. Hopefully it will help you.

This is a simple function which can be used when you have a form for your users to post their message and you want to censor every badwords that they might write on that form. <?php /*********************************************** * Snippet Name : censorMsg * * Scripted By : Hermawan Haryanto * * Website : http://hermawan.dmonster.com * * Email : hermawan@dmonster.com * * License : GPL (General Public License) * ***********************************************/ $bw = "words|seperated|by|pipe|symbols"; function str_repeats($input, $mult) { $ret = ""; while($mult>0) { $ret .= $input; $mult --; } return $ret; } function censorMsg($msg, $replacement="*") { global $bw; $badwords = explode("|", $bw); $eachword = explode(" ", $msg); for($j=0;$j<count($badwords);$j++) { for($i=0;$i<count($eachword);$i++) { if(is_int(strpos(strtolower($eachword[$i]), $badwords[$j]))) { $msg = eregi_replace($eachword[$i], str_repeats($replacement, strlen($eachword[$i])), stripslashes($msg)); } } } return $msg; } $msg = $_POST["msg"]; if (isset($msg)) { $msg = censorMsg($msg,"*"); print "Your posted Message :<br>".$msg; } ?> <form method="post"> <textarea name="msg" cols=50 rows=10></textarea><br> <input type="submit" value="Censor It"> </form>

This function allows you to pass in: <ul> <li>name <li>table <li>SQL statement <li>id </ul> to generate a select box dynamically.

This function updates the second box, depending on the selection of first box. Adapted from code by Leon Atkinson. ### this neat javascript function I adapted from Leon Atkinson's code updates the second dropdown box ### (subcategory) depending on what is selected in the first (category). ### this function obviously needs to be contained in a form. ### ### array_key_ID is an array of the unique identifiers of the subcategory ### array_cat is the array of categories ### array_subcat is the array of the subcategories ### num_in_array is the total number of items in the array ### distinct_cats is the number of unique items in the category field ### MaxItems is the maximum number of items that can occur in the subcategory dropdown box ### ### Works in IE 4+ and Mozilla 0.9.9+ ### Not currently working in Opera (6.02) function dynamicboxes ($array_key_ID, $array_cat, $array_subcat, $num_in_array, $distinct_cats, $MaxItems ){ print "<SCRIPT Language=\"JavaScript\">\n"; print "function UpdateSubCat()\n"; print "{\n"; print "\tvar SubCat = document.choose_category.subcat.options.length;\n"; print "\twhile(SubCat > 0)\n"; print "\t{\n"; print "\t\tSubCat--;\n"; print "\t\tdocument.choose_category.subcat.options[SubCat].text = '';\n"; print "\t\tdocument.choose_category.subcat.options[SubCat].value = '';\n"; print "\t}\n\n"; print "\tdocument.choose_category.subcat.options[0].selected = true;\n\n"; print "\tvar CatSelected = 0;\n"; print "\twhile(document.choose_category.cat.options[CatSelected].selected==false) CatSelected++;\n\n"; $StoreCat = ""; $SubCatCount = 0; $RowCount = 0; while($RowCount < $num_in_array) { $item_key_ID = $array_key_ID[$RowCount]; $item_Cat = $array_cat[$RowCount]; $item_SubCat = $array_subcat[$RowCount]; if($StoreCat != $item_Cat) { if($StoreCat != "") { print "\t}\n"; } print "\tif(document.choose_category.cat.options[CatSelected].value == '$item_Cat')\n"; print "\t{\n"; print "\t\tdocument.choose_category.subcat.options[0].value = 0;\n"; print "\t\tdocument.choose_category.subcat.options[0].text = 'Choose a subcategory';\n\n"; $StoreCat = $item_Cat; $SubCatCount=1; } print "\t\tdocument.choose_category.subcat.options[$SubCatCount].value = '$item_key_ID';\n"; print "\t\tdocument.choose_category.subcat.options[$SubCatCount].text = '$item_SubCat';\n\n"; $SubCatCount++; $RowCount++; } print "\t}\n"; print "}\n"; print "</SCRIPT>\n\n"; print "<SELECT NAME=cat onChange=\"UpdateSubCat();\">\n"; print "<OPTION VALUE=0>Choose category"; $RowCount = 0; while($RowCount < count($distinct_cats)) { print "<OPTION VALUE=\""; print $distinct_cats[$RowCount]; print "\">"; print $distinct_cats[$RowCount]; print "\n"; $RowCount++; } print "</SELECT>\n"; print "<BR>"; print "<SELECT NAME=subcat >\n"; $RowCount = 0; while($RowCount <= $MaxItems) { print "<OPTION VALUE=$RowCount>"; print "Subcategory\n"; $RowCount++; } print "</SELECT>"; print "<SCRIPT Language=\"JavaScript\">UpdateSubCat();</SCRIPT>\n"; }
This function is great for when you have a multi-page form such as an application. This function forwards fields on one page to hidden fields on the next page, and so on. Very simple to call. The beauty of it is, it also will handle arrays with multiple dimensions. If you have a field with the same name on the next form, it's a good rule to call field_forwarder() at the BEGINNING of your form so that when that form is passed, the field (with the same name) will overwrite the previous form. It's also good to put field_forwarder() at the top so the final page will have all the fields in the order of the application. This is a recursive function, i.e. it re-calls itself when it encounters form elements that are arrays such as: Finally, if you wish to print out PHP code of the array instead of hidden fields, add this line right before you call field_forwarder(): $FFoutputType = 'print'; and it will print out, in text form, the values of the fields as php variables -- this is great for storing php code in a database. <?php function field_forwarder(){ global $_POST, $rEM979, $FFoutputType; //get the arguments passed $argList = func_get_args(); //globalize any other set of instructions if(count($argList)){ eval('global $' . $argList[count($argList)-1] . ';'); } //set the default set of values to convert if(count($argList)==0){ //if the function is initially passed without parameter we're looking in $_POST $argList[0] = '_POST'; $startValue = $_POST; if(sizeof($startValue)==0){return false;} }elseif(count($argList)==1){ eval( '$rEM979["' . $argList[0] .

Over the summer I wrote a utility class to make it easy to pull information from HTML forms and place into databases and do various manipulations on arrays without having to write much special code for each case. I have used this class library from everything from a member management database to secure credit card updating utility. Key features: 1. Return array data where field keys match a certain prefix such as CUSTOMER_, CREDITCARD_ (even from HTTP_POST_VARS). 2. Create MySQL Insert, Update, and basic Create Table statements from associative array data. Note: There is a lot of code here and it is very useful. The documentation could definitely be better, but I do not have enough time to document this as well as I would a commercial product for the time being. The code is intended to be readable and each function should have a JavaDoc like header. I welcome comments and/or additions to this library class. <?php /** * Utility Form Data Collector and Array-to-SQL Statement Generator * Version 1.32 * Last Updated: 9/23/2002 * 9/5/2002 * 8/12/2002 * * Copyright 2001-2002 Frank Rietta and Rietta Solutions * * LICENSE * This software is provided 'as-is', without any express or implied * warranty.

I was not so comfortable with this one( http://zend.com/codex.php?id=59&single=1 ) So, I simplified the one enough to feed me. // Written by kyong@pauline.or.kr function print_option($name, $options) { // php4 friendly global $$name; echo "<select name=\"$name\">\n"; foreach ($options as $value => $text) { printf ("<option value=\"%s\" %s> %s </option>\n", $value, $value == $$name ? "selected":"", $text); //selected one goes first } echo "</select>\n"; } function print_option2($name, $options) { // php3 friendly global $$name; echo "<select name=\"$name\">\n"; while (list ($value, $text) = each ($options)) { printf ("<option value=\"%s\" %s> %s </option>\n", $value, $value == $$name ? "selected":"", $text); } echo "</select>\n"; } function print_option3($name, $value, $text) { // your flavor? global $$name; if (count($value) != count($text)) { echo "Should be equal in array size"; exit; } echo "<select name=\"$name\">\n"; for ($i=0; $i<count($value); $i++) { printf ("<option value=\"%s\" %s> %s </option>\n", $value[$i], $value[$i] == $$name ? "selected":"", $text[$i]); }
