Rename File on upload

I have a work-around for this which does well for us. I’m not sure if you’ll want to dive in to this level though.

In wp-content/plugins/entrywizard/classes/ewz-webform.php
Change the line
$fp = popen("zip -0 -j -q - $fnames", 'r'); // see testing notes
To
$fp = popen("/usr/local/bin/createZipForCompetition.sh $fnames", 'r'); // see testing notes

Then create the file /usr/local/bin/createZipForCompetition.sh as follows

#!/bin/bash

# Given a list of files, create a zip suitable for download
# One of the files will be a CSV

TMPDIR=/tmp/CompetitionZIP_$$
mkdir $TMPDIR
mkdir $TMPDIR/orig
mkdir $TMPDIR/out
mkdir $TMPDIR/out/fullname
mkdir $TMPDIR/out/titleonly

# store arguments in a special array
args=("$@")
# get number of elements
ELEMENTS=${#args[@]}

# echo each element in array
# for loop
for (( i=0;i<$ELEMENTS;i++)); do
        # echo "Processing ${args[${i}]}"
        # echo cp "${args[${i}]}" $TMPDIR/orig/
        cp "${args[${i}]}" $TMPDIR/orig/
done

# We've now copied all the files into the target location
# Next we need to process the CSV file

LINECOUNT=<code>cat $TMPDIR/orig/*.csv | wc -l</code>
# echo "Lines to handle = $LINECOUNT"

#Create the data files
cat $TMPDIR/orig/*.csv | csvcut -c "Display Name" > $TMPDIR/orig/_DISPLAYNAME.TXT
cat $TMPDIR/orig/*.csv | csvcut -c "Filename" > $TMPDIR/orig/_FILENAME.TXT
cat $TMPDIR/orig/*.csv | csvcut -c "Title" > $TMPDIR/orig/_TITLE.TXT
cat $TMPDIR/orig/*.csv | csvcut -c "Tp" > $TMPDIR/orig/_TYPE.TXT

for (( i=2;i<=$LINECOUNT;i++)); do
        IMAGEAUTHOR=<code>cat $TMPDIR/orig/_DISPLAYNAME.TXT | sed -n -e 1p -e ${i}p | tail -n 1 |  tr &quot;<>:\&quot;/\\|?*_&quot; @</code>
        IMAGEFILE=<code>cat $TMPDIR/orig/_FILENAME.TXT | sed  -n -e 1p -e ${i}p | tail -n 1</code>
        IMAGETITLE=<code>cat $TMPDIR/orig/_TITLE.TXT | sed  -n -e 1p -e ${i}p | tail -n 1 | tr &quot;<>:\&quot;/\\|?*_&quot; @</code>
        IMAGETYPE=<code>cat $TMPDIR/orig/_TYPE | sed  -n -e 1p -e ${i}p | tail -n 1 |  tr &quot;<>:\&quot;/\\|?*_&quot; @</code>
        RINDEX=<code>od -A n -t d -N 4 /dev/urandom | tail -c 6</code>

        #  echo "===== ENTRY $i"
        #  echo "Author     : >$IMAGEAUTHOR<"
        #  echo "Filename   : >$IMAGEFILE<"
        #  echo "Title      : >$IMAGETITLE<"
        #  echo "Type       : >$IMAGETYPE<"

        if [ -z "$IMAGEAUTHOR" ]
        then
                #  echo "***** NO AUTHOR - giving up"
                continue
        fi

        if [ -z "$IMAGEFILE" ]
        then
                #  echo "***** NO FILE - giving up"
                continue
        fi

        if [ -z "$IMAGETITLE" ]
        then
                #  echo "***** NO TITLE - giving up"
                continue
        fi

        if [ -z "$IMAGETYPE" ]
        then
                # echo "***** NO TYPE - creating a standard name"
                TARGETFULL="${IMAGETITLE}_${IMAGEAUTHOR}.jpg"
                TARGETSHORT="${RINDEX}_${IMAGETITLE}.jpg"
        else
                # echo "***** HAS TYPE - creating an extended name"
                TARGETFULL="${IMAGETITLE}_${IMAGETYPE}_${IMAGEAUTHOR}.jpg"
                TARGETSHORT="${RINDEX}_{IMAGETYPE}_${IMAGETITLE}.jpg"
        fi

        SOURCEFILE=$(printf '%q' "$IMAGEFILE")

        TARGETFILEFULL=$(printf '%q' "$TARGETFULL")
        MYCMDFULL="cp $TMPDIR/orig/${SOURCEFILE} $TMPDIR/out/fullname/${TARGETFILEFULL}"
        eval $MYCMDFULL

        TARGETFILESHORT=$(printf '%q' "$TARGETSHORT")
        MYCMDSHORT="cp $TMPDIR/orig/${SOURCEFILE} $TMPDIR/out/titleonly/${TARGETFILESHORT}"
        eval $MYCMDSHORT
done

cd ${TMPDIR}/out

zip -r -q -0 ${TMPDIR}/generatedzip.zip *
cat ${TMPDIR}/generatedzip.zip

cd /

rm -rf ${TMPDIR}

You may need to update to grab the specific columns you want from the CSV file generated for inclusion in the filename.

We run this on a Linux hosted environment and not hit any problems yet. We strip out the problematic characters from the titles before renaming the file (tell people that they can’t have things like * < > | etc).

Works for us, but we need to remember to re-modify the plugin code every time we update.

To Wildcardinal, if you make changes to the EW code, what happens with a new update from Josie?
