Kiongkavi Posted April 10, 2007 Share Posted April 10, 2007 Dear all, my PHP aims to update a MySQL database by selecting record one by one and modify then save. let's begin from the very beginning, current behavior is that if initial value from id=99, the UpdMySQL of id=99 will be perform OK with row 99, but the $cat/$ori in row 100 will also be changed to the same as row 99.then content("body") of row 99 will be shown again(thepage keep no change ), although in fact, row 100's id2=1; then when DelMySQL/UpdMySQL/AgrMySQL is performed, the update fields go to the next row of the row which content("body") is shown on the website. In other words, in front end, #K-th record is shown but the update will go to #(K+1)-th record. <?php //Connect to database $connect = mysql_connect("andy","kiong","Password")or die("Could not connect : " . mysql_error()); ; mysql_select_db("kiong_userinfo",$connect)or die("Could not connect : " . mysql_error()); // select a record $result = mysql_query("SELECT * FROM putonServer where id2=1", $connect); $newline = "<br />"; $row = mysql_fetch_array($result) or die(mysql_error()); $this_id=mysql_result($result,0,"id"); $this_body=mysql_result($result,0,"body"); //show the content of the record echo $this_id; echo $newline; echo $this_body; ?> <HTML>. <!--Show the webpage, where the content(body field of putonServer) in the record will be shown, Three button: Discard(B0),Agree(B1) and Update(B0) will be shown as well --> .....<HTML> <?php //Make a deleted mark for the record which should be deleted from the database function DelMySQL($this_id,$connect) { $next_id=$this_id+1; $query_B0="update putonServer SET id2=7 where id='$this_id'"; $query_B0_2="update putonServer SET id2=1 where id='$next_id'"; $result_B0=mysql_query($query_B0,$connect); if (!$result_B0) { die ('Puke, Wrong2 ' . mysql_error()); } $result_B0_2=mysql_query($query_B0_2,$connect); if (!$result_B0_2) { die ('Puke, Wrong ' . mysql_error()); } } //Make an agree mark for the record which should be kept no change in the database function AgrMySQL($this_id,$connect) { $next_id=$this_id+1; $query_B0="update putonServer SET id2=7 where id='$this_id'"; $query_B0_2="update putonServer SET id2=1 where id='$next_id'"; $result_B0=mysql_query($query_B0,$connect); if (!$result_B0) { die ('Puke, Wrong2 ' . mysql_error()); } $result_B0_2=mysql_query($query_B0_2,$connect); if (!$result_B0_2) { die ('Puke, Wrong ' . mysql_error()); } echo "Processoooo".$newline; echo $this_id; } //modify the selected row in a database function UpdMySQL($this_id,$connect,$cate,$orie) { $next_id=$this_id+1; $query_B2 ="UPDATE putonServer SET category='$cate',orientation='$orie' where id='$this_id'"; echo $this_id.$newline; $result_B2=mysql_query($query_B2,$connect); if (!$result_B2) { die ('Puke, Wrong2 ' . mysql_error()); } $query_B2_1="update putonServer SET id2=4 where id='$this_id'"; echo $this_id.$newline; $query_B2_2="update putonServer SET id2=1 where id='$next_id'"; echo $this_id.$newline; $result_B2_2=mysql_query($query_B2_2,$connect); if (!$result_B2_2) { die ('Puke, Wrong ' . mysql_error()); } $result_B2_1=mysql_query($query_B2_1,$connect); if (!$result_B2_1) { die ('Puke, Wrong2 ' . mysql_error()); } } // When different button is clicked, do different action on the database if($_POST[b0]){ DelMySQL($this_id,$connect); } if($_POST[b1]){ AgrMySQL($this_id,$connect); } if($_POST[b2]){ UpdMySQL($this_id,$connect,$_POST[R2],$_POST[sliderinput22]); } ?> <Description for the database> +-------------+------------------+------+-----+--------- +----------------+ | Field | Type | Null | Key | Default | Extra | +-------------+------------------+------+-----+--------- +----------------+ | id | int(11) | | PRI | NULL | auto_increment | | id2 | int(11) | | | 0 | | | users | int(10) unsigned | | | 0 | | | date | text | YES | | NULL | | | time | text | YES | | NULL | | | docuname | text | YES | | NULL | | | body | text | YES | | NULL | | | orientation | int(11) | | | 0 | | | category | int(11) | | | 0 | | +-------------+------------------+------+-----+--------- +----------------+ Quote Link to comment Share on other sites More sharing options...
btherl Posted April 10, 2007 Share Posted April 10, 2007 Try printing out your queries. I notice that you print out the values for your queries, but it's much MUCH better to print the queries themselves. I am particularly suspicious of this code: $query_B2_2="update putonServer SET id2=1 where id='$next_id'"; echo $this_id.$newline; The query uses $next_id, but you echo out $this_id (for debugging?)

Kiongkavi Posted April 10, 2007 Author Share Posted April 10, 2007 I did Print them out. it is OK, $next_id's value is $this_id+1. the print out is for debugging.. You are right. Quote Link to comment Share on other sites More sharing options...
btherl Posted April 10, 2007 Share Posted April 10, 2007 Hmm.. is the problem that you read the data from the database before doing the update? Quote Link to comment Share on other sites More sharing options...
Kiongkavi Posted April 10, 2007 Author Share Posted April 10, 2007 now, at the beginning, it update OK when it initially starts from Record #99, but after update Record #99 and refresh page, the content of Record #99 will still be there(shown on the webpage), and in the back end(MySQL database) it is Record #100 where id2=1.. the situation following is same: front end(Webpage): Record #K, back end(MySQL database): Record # K+1, and the update still on row Record # K+1, Quote Link to comment Share on other sites More sharing options...
Kiongkavi Posted April 10, 2007 Author Share Posted April 10, 2007 Well, it is normal way that : check the record before we update it, right? Quote Link to comment Share on other sites More sharing options...
